Baba Is You - Hempuli
A new patch with mostly bugfixes will go live sometime soon. There's one change that may affect people who've made custom levels that I referred to in the previous patch notes, and I wanted to point it out again here to avoid extra confusion/frustration.

To prepare for the official editor, the next patch moves sprite files that were in the main level pack's folder but that weren't meant to be specific for that level pack into the general sprite folder. That means that levels that assumed that their sprites are in the level pack -specific folder will load erroneous sprites. No crashes or errors, hopefully, they'll just not look like they should.

Hopefully this won't cause too much trouble. There will probably be some upcoming changes that similarly impact things people have already made; I'll try to mention them beforehand.

Baba Is You - Hempuli
Version ID: HJ
(You can press left control + J to view the version ID while in the main menu.)

Fixes and tweaks:
- Fixed a small ending-related visual bug if the grid is enabled
- Fixed a rather severe oversight where certain rules were adding events to the undo buffer in the wrong order, causing errors
- Added an additional check for situations where the player would've cleared an area but due to e.g. level repositioning between versions didn't get the flower for it
- Fixed a bug where floating Baba and a weak Wall would have a mystery interaction
- In certain cases where the game would freeze, it displays a special effect instead (this'll be expanded on and it might not appear in the game at the moment)
- Large underlying code reworking related to conditionals, not relevant in the game right now but it's work for the future
- Related to the above, conditionals with parameters behave in an equivalent way whether the condition has a Not or not
- Fixed the word Facing not accepting directional words
- Related to above, made Empty Is <direction> work mostly as intended
- Fixed "Empty Is X" particle effects appearing everywhere even if Empty had a conditional word

Level adjustments:
- Whoops (a very small change; level found in ???)
- Collaborative effort (removed an unintended approach, found in Depths)
- Acrobatics (one of the changes listed above broke the level, found in Meta)
- Tectonic Movements (fixed a small readability issue, found in Mountaintop)
- Seeking Acceptance (made the level more symmetric, purely a visual thing, found in Mountaintop)
- Heavy Cloud (this might actually be a large change, found in Space)
- Keke And The Star (fixed an unintended solution, found in Chasm)
- The Heist (removed red herrings, found in Cavern)
- Gallery (this'll need more work, but made the limits of the level clearer, found in Center)
- Backstage (fixed a fairly tiny alternative solution, found in Cavern)
- Maritime Adventures (removed an unnecessary element, found in Garden)

For modders:
- I will start working on features related to making the game ready for the level editor such as adjusting the data structuring; these changes will almost inevitably break mods. I'll try to list in these patch notes changes that I think might be like this. My apologies in advance.
- More modder-specific patchnotes will be entirely spoilered, so behold:
- "Not On Keke And Baba" now requires the object not to be on both at the same time instead of either one to make the functionality equivalent to "On"; all conditionals with parameters work now the same way.
- The "operatortype" -value has been removed from values.lua; it made the system needlessly more complicated. If you want to change objects to conditionals, use the 'type' value. If you want a conditional with parameters to allow other parameters than objects, edit the level file and add changes "argtype" and "argextra".
- I'll be moving sprites from the Data/Worlds/baba/sprites/ folder to Data/sprites/ because most of the ones in the former aren't really meant to be specific to the main game.

I meant to wait a bit longer and have a larger update done, but I wanted to get one of these changes out faster so here we are.

- Added guest credits to "Across" (level in the ??? area.) Apologies to Corey Martin for missing that when adding the level.
- A relatively large underlying code rework to prepare for certain even larger future changes. This will break mods, but might cause other issues as well. Apologies for the trouble; once I get this and that later additional change done things should* be more stable.

* Hopefully

Fixes etc:

(It has been proven that Ghost Friend is haunted and thus it can stay the way it was as a very early Halloween thing)
