This update might not seem like a big one from the first glance - not so many content additions, mostly tweaks and bugfixes. But there is one major tweak that will change how Sipho is played - Snacks now restore Nutrition if you have fallen below your recorded maximum!

That's right - if you lose half of your colony, you can still get it back by consuming much more abundant Snacks. This helps to keep achieved progress and avoids soft-locks where one is unable to re-grow parts without killing whole Siphos. This change has been suggested in many forms by you, players, and we had to figure out how to make it work intuitively. Nutrition Orb now displays missing nutrition as a red bar above your current nutrition, as well as indicates how much nutrition you lose or gain by doing actions:

Notice how picking up additional Snacks don't provide nutrition beyond the red zone. We hope that these changes will remedy some of unfortunate moments due to volatile nature of Zooids.

Cra'Than Sizzler zooid has received a facelift - it has received a better visual effect to show what has been affected by the shock. Affected zooids are no longer random - now closest zooids and their neighbors are shocked.

Additionally, Sizzler stun duration is now affected by Ranged Power stat, which increases stun duration by 1 second for each stat point.

Changelog in detail:

• Show nutrition delta on Nutrition orb
  
• Add utility to find neighboring zooids up to zooid count
  
• Sizzler is now affected by Penetration - how many zooids it affects and Ranged Power - stun duration
  
• Add Development-only Penetration powerup
  
• Shell now protects from Sizzler stun on application rather than in update step. This allows adding additional stuns on the same frame
  
• Add tooltip explaining lost wealth to Nutrition orb
  
• Search for tooltip instances in parent game objects too. Tweak some UI objects to not provide unrelated tooltips
  
• Return ungrowth nutrition immediately when ungrowing zooids
  
• Fix plant leaves looking weird when rotten
  
• Food should not block growing new zooids
  
• Reset player's MaxWealth when growing from layout or toggling unlimited nutrition in Aquarium

• Add cooldown and energy cost to skill description shown in zooid tooltip
  
• Increase base energy regeneration to 25 (up from 20)
  
• Chitin shell is removed when it protects from Sizzler attack
  
• Apply poison to nearby targets on initial poison spawn. Makes using Mines up close easier
  
• Do not twin-stick turn Sipho while game is in Growth mode transition
  
• Prewarm poison pill so it instantly appears as intended
  
• Sipho Death events now carry information about killer. Prevent other Siphos picking up consumables which they don't own for 1 second
  
• Make damage powerup triangles two-sided so they don't disappear when consumable is flipped
  
• Cra'Than hole spawn progress decreases instead of being reset when something covers it
  
• Increase Event System Drag Threshold to 15 (from 5)
  
• Rearrange development menu spawn items
  
• Interactive area is deactivated if main sipho dies
  
• Death cancels whirlpool diving
  
• Better debug for Graphics Connector and Swarm Minion to catch reported exceptions
  
• Break down Head Selection intialization code for debugging
  
• Fix null key paths after starting new game
  
• Fix Vagorians not being spawned
  
• Nutrition orb shows mising wealth
  
• Update UI default shader

• Update engine to 2020.3.2f1
  
• ignore Debug folder
  
• Bring back Nerverfiber heal to 2. Do not restore nutrition through heals

Last bugfix and quality updates for 0.7.8 are here! Next update is going to be about addressing surfacing common feedback - enemy behavior and nutrition drops, stay tuned.
- Use optional debugging menu for debugging some game systems that were previously just drawing their own debug things and cluttered whole screen
- Fix Buginis environment leaves for some reason being 2x smaller than intended
- Heads no longer deal damage on touch. Tweak head graphics to appear above connections
- Spike fixaroo 5: Electric boogaloo - reduced launch force and drag for spike tip to make it match expected distance and be more stable
- Do not change Rigidbody type and disable them entirely when sinking. Should improve performance on Area Clear
- Fix error throw if growing through Growth point failed
- Clip transparent Zooid pixels
- Fix Zooid growth growing on different growth point than it previews
- Fix growth point search for peapods
- Update Sipho structure data when growing from Layout
- Make Cra'Than areas scale as the rest of the areas
- Make zooid repositioning work with relevant zooid search
- Improve Growth Point UI search by taking their relevant direction into account
- Improve zooid highlights by highlighting "main" connection zooid
- Remove duplicate Layout and update original "Genial Advena Nosher"
- Clamp healing to max health to prevent overhealing
- Fix old builtin layout Advena Slicerness
- Update Sipho structure data on demand
- Only upgrade layouts if their version is lower, rather than not equal to current
- Update total Siphonophore movement power every frame instead of on structure change

This update addresses some requests for better control binding - you can now bind default keys for skills. Dive action keybind has been also separated from Confirm button - so it will be possible to bind <Space> to another key for gameplay and still use it for confirming UI navigation.

Big refactor has been performed on how Layout data stores zooid angles - we had an issue where growing a perfect circle with 22.5 degree turns was impossible - it would get rounded up or down. We had to update how Layout data is stored which means it will no longer be backwards compatible with previous versions once new version is loaded up.

• Buginis Boss 1 attacks back
  
• Add option to limit total spawns of an Enemy Spawner. Limit Alpha spawns to 1 per level
  
• Angle-clamp zooid angles in layouts to 1440 degrees
  
• Increase exported Layout position precision to 3 fraction digits (up from 2)
  
• Optimize boss skill range checks by exiting early if skill is unavailable. Should improve Buginis Boss 3 performance
  
• Fix zooid angle rounding error by internally storing zooid angles 4 times higher, to support up to 32 rotations as integers
  
• Fix spacing in UI Elements by adding minimum height as font size
  
• Add missing sprites for Controller key binds. Allow setting default keybinds for skills in Options menu
  
• Add separate Dive button keybind

We had an opportunity to make several small fixes to a part of issues we had reported. Enjoy!

• Delay Buginis Swarm boss obstacle checks up to over 10 fixed frames to easen CPU load
  
• Don't spawn 30 shockwave particles, spawn 1 instead and as twice as distorting - fixes lag in some boss fights
  
• Add missing pickup and place sounds for Zooids. Add test for missing zooid sounds
  
• Tweak visual connection distances for Claw and Peapod
  
• Add Head Selection debug messages to help debugging game launch error
  
• Remove duplicate event system in tutorial level
  
• Swarmer improvements - faster minion turning, prioritize zooids over everything else, move at 75% speed (rather than 15%) when on obstacles
  
• Use slider joint to limit spike movement along extension axis. Add drag when it's extended so it doesn't flail as much
  
• Set Growth UI object name to contain zooid that will be grown name for easier debug

We can finally say that the latest version 0.7.8 is a direct improvement over previously available Sipho version 0.6.9 and time has come to make it available for everyone! There are loads of new content and tweaks in this update:

New and higher resolution graphics for all environments. Deeper objects are now affected by parallax effect. Some of new objects have special properties - Bones spawned in Advena areas are breakable, Cra'Than Holes spawn food if they are unblocked. And all of these environments are no longer visited in fixed order - this improves replayability and allows us present more varied enemies. Previously, Saenus Beefuorus were only seen in first levels and they barely fought back. Now, you might encounter them in later giving a much better fighting chance for that breed.

9 new bosses were added for each difficulty tier, adding up to a total of 13. Some of boss designs were based on the winners of community boss design competition. Boss fight arenas also use new environment features to spice up the strategy. We will be further polishing these fights - we want to these fights to encourage varied strategies and break pace from regular open-area battles. Boss fights are also great for experimenting with different mechanics in isolated area which we might bring later to the rest of the game.

Extended connections for structure parts was a small change which unlocked exponentially more possibilities of designing your SIpho. It was once a cursed growth technique of experienced players, which required placing and removing structure Zooids in a specific way to create farther connections than usually possible. Thanks to our community, it has been implemented to work out of the box:

Here you can see Advena structures placed further apart to allow Spikes sliding through

Special properties for movement Zooids were added to differentiate movement zooids further. They have the following effects:

• Advena movers regenerate energy on hit - we hope that this will play well with Advena's aggressive idea
  
• Saenus movers have much stronger Dash skill effect - acting like real-life squid jets
  
• Buginis movers decrease cooldowns of neighboring zooids by 10% - plays well with Buginis skill
  oriented breed. Since skills are not separated for each zooid and connections can be more intricate, mean value for cooldowns is used. For example if you have a Flak with 110% Cooldown Recovery and another with 120% CR, skill cooldown will be reduced by 15%.
  
• Cra'Than movers have additional connection points - crazy, we know, let's see how this works!
  
• Vagorian movers regenerate health - destined to bump into spiky things, Vagorians have evolved to regenerate their wounds,

Improvements worth mentioning:

• Rebalanced energy use of skills to scale better with smaller and larger Siphos. Read more about the change in previous announcement
  
• Added new Cooldown Recovery stat which improves your Skill cooldown duration
  
• New type of Siphonophore enemy - Polyp, which are stationary, turret-like Siphos. They don't think much and certainly don't move. Currently they can be found in single boss fight and spawned in Aquarium. In future versions we might use them as enemies in regular areas as well as in different boss fights.
  
• Zooid unlock drop options increase with each level - first boss drops two zooids to choose from, second one drops three and so forth - we hope this gives more freedom and incentive to continue playing in further levels.
  
• You now keep all adapted Zooids throughout runs. It means that with every replay extra Zooid selection list grows with new zooids. We thought that previous behaviour was just unpleasant for inexperienced players and nothing of value for experienced ones.
  
• New powerups - Melee and Ranged Damage, Cooldown Recovery and Range

Known issue:

• With increased amount of environment objects performance can get worse once Area is Cleared. We are looking into how to improve both performance and experience of being told that the level has ended.

The most recent changes that haven't been mentioned in previous updates:

• Spawn Cra'Than boss 3 whirlpool in the middle of arena

All of changes made since 0.6.9 can be found here.

As we are getting closer to 0.7.x release to wide masses we are focusing on doing last touches of polishing roughest edges. Remakes of Cra'Than areas and boss polish will be coming after we release this update to the default branch - they are good enough to not lower the quality bar compared to widely available version 0.6.9.

Another fight based on boss design contest has been added to the game! This time it's The Gemini, create by Popcorn Dust!
The original design was solid - boss behaviour promotes interesting strategies fighting them. And there is a lot of potential for lore. We deviated a bit from original by making the second Gemini an invert of the original design:

The fight might be fiendishly hard or cake-walk easy. We will be monitoring feedback and tweaking this boss in the future!

The arena features new Cra'Than environment objects which will be added to existing levels to spice up variety. We are very happy how Tentacles have turned out to be. If they prove to be stable enough for such physics-based action as Sipho has, we might add stronger interactions with them - some might get annoyed and push objects away. We have also added Holes which sometimes spit out useful powerups to aid you in your fights.

Aquarium Layout Browser has gotten a little bit of love - it can now be searched and sorted by names or values of Layouts. More Aquarium functionality improvements are planned in the future.

Have a go at all changes we've made:

• Enable random motors on tentacles to make them move
  
• Cra'Than boss battle 2

Initial release of so-called Swarm - Buginis third boss fight has shown several things it needs to be improved upon. Its AI was tweaked to have a goal inside the Boid-brain to attack its current target Siphonophore - you, the player. Previously it would override Boid flocking behavior to go straight to its target, if it is in vision, and it would cause clumping together with other agents. Clumping up should now happen much less often.
Another interesting change was addition of Camera position and size overrides for boss fights. We can now increase zoom range in arenas without having to design environment outside of playable areas - the camera is simply pushed away from the edge, towards arena contents. This increases vision of important arena parts and allows us to tell the story using the environment more clearly.

• Beautify Buginis boss 3 arena
  
• Add plant Nest formation
  
• Add damaged effect to Sipho container
  
• Fully zoom out when using custom views - makes boss fight zoom consistent
  
• Make Buginis Swarm boss movement fully boid based with goal support
  
• Sipho eggs spawn siphonophores using their own direction
  
• Tweak Buginis Boss 2 arena camera limits
  
• Add Camera Follow Overriders to boss arenas to limit vision only to relevant area and allow zooming out further
  
• Tweak Buginis Swarm boss behavior to include player as goal in Boid simulation
  
• Workaround Sipho size being very large after boss area load by skipping a frame
  
• More Rect utility tests
  
• Add Camera Follow Overrider to enable custom camera control for boss fights
  
• Remove explosive sweeping from Sipho container

After many tweaks, third Buginis boss fight is now in the game! It is based upon Murderswarm design by TIC. We have let ourselves experiment with it a bit and we feel that it is going to be yet another unique boss fight.

The boss fight implementation differs from original by being Buginis, rather than Vagorian breed. On paper, swarm-based AI might sound easy to do, but it required quite a bit of tweaking to get it somewhat right in the game. It turned out alright and we are pretty happy with the result - the Swarm behaves believably in confined arena and is a threat to the player.

While tweaking and improving Swarm's behavior we saw potential of using the same method of control for friendly Siphos in Aquarium. Smaller Siphos would follow larger ones, including player's Sipho, which would have some influence upon the rest of the Swam. That would turn into a herd-management minigame if you want to keep your own Swarm together and fight other Siphos. These Aquarium improvements would come after we finish with non-linear levels in 0.7 versions.

• Less error prone way of applying zoom to view margins
  
• Reduce duration for camera animation if there is no spawn animation
  
• Use boss battle zoomout for other bosses
  
• Allow overriding zoom level for camera follow. Use zoom overrides for boss battle initial camera animation
  
• Swarm AI and arena improvements
  
• Add Buginis Boss 3 Swarm Layouts
  
• Do not save game while boss fight has not ended yet. Deterministically select zooid unlock drops
  
• More appropriate way of saving Boss Battle state
  
• WIP Buginis swam boss - swap arena art to Buginis environment, boid movement improvements, spawn swam from destroted eggs
  
• Add Destructible Sipho Container which spawns Siphos upon destruction
  
• Add HUE shift property to environment shader
  
• Add test for finding duplicate Environment Object IDs and fix them
  
• Swarmer Boid AI is now Faction based - boids will follow anyone in their faction
  
• Add Intended Rotation property to Siphonophore
  
• Update Siphonophore physical radius each frame instead of on Structure change

We had a little hidden update with several improvements:

• Use automatic Graphics API for MacOS
  
• Move LUTs to Textures directory out of PostProcessing
  
• Show Builtin layouts first if there are no manually saved layouts in Layout Browser
  
• Rename few particles options
  
• Re-gather shader
  
• WIP Buginis boss
  
• Add some particle graphics options
  
• Remove two unused texture lookups in whirlpool mist shader
  
• Choose another enemy spawner layout if enemy spawner fails to spawn in 100 tries
  
• Increase level end timeout to 30 minutes

Greetings everyone! Happy past holidays and new year! Now that the festive distractions are gone we can go back to improving Sipho.
One thing that has been bothering us for a while, was how hard the game is when your Sipho is little. It is hard to balance the game to play well when your creature colony is small, made out of few movers and a weapon, and large, having dozens of buffed-up(tm) weapons, efficient energy regeneration... and skills cost the same fixed amount. So we have finally gathered our courage to attempt at balancing that through skill cost. Now, most of the skills have a lower base cost and grow their cost with each zooid:
As you can see, new skill costs match old ones are around 4-5 zooids. We hope that this skill cost rebalance will feel more realistic and allow better difficulty scaling for different Sipho sizes. We will monitor experience and adjust these skills costs accordingly - let us know how they feel!

• Correctly decrease poison duration by 30% for each stack
  
• Balance sum skill costs around 4-5 zooids rather than 2-3. Generally makes skills cheaper
  
• Heads by default have 0 melee damage, but can deal damage if buffed.

• Fix some environment objects remaining collidable after level ends forcefully
  
• Fix environment some objects not fading out correctly

• Fix Swarmer minion animations lagging behind. Movement Force stat no longer affects Swamer Minion speed
  
• Tweak Saenus boss 2 arena to make it unescapable
  
• Add Important setting on spawners and mark obstacle spawners as important. Do not spawn enemies inside chunks of important spawners that have not been loaded yet. Fixes rock-squished enemies
  
• Fix error when kill point receiver tries to unsubscribe from nonexisting Siphonophore
  
• Swarmer minions now crawl on top of obstacles
  
• Add timer based melee damage to all heads

• Pusher Penetration stat allows pushing more objects at full force by 30% per stat
  
• Improve whirlpool particles
  
• Zooid description shows Penetration stat as relevant if Ranged stat is non-zero

• Added tooltip translations
  
• Show skill cooldown difference in tooltips. Tell players how to rebind skills
