What the developers have to say:

Why Early Access?

“As a single player game, I wanted to wait until the player could have an essentially complete experience when playing through the Story Mode. As such, the game is nearly complete and all that's needed is to polish things up a bit and get some feedback on certain areas of the game. I want to take my time making everything as perfect as I can make it, but I also want to get the game into the hands of hardcore platformer fans so that they can enjoy playing the game. There are several aspects of the game that I feel will benefit from more community feedback as I continue to polish the game. I look forward to engaging with the community to build The True Slime King into the best game it can be.”

Approximately how long will this game be in Early Access?

“I'm aiming for The True Slime King to leave early access in early 2019. I'd say over 90% of the game is complete at this point, it's just a matter of polishing up a few graphics here and there and adding all of the features that will make for truly complete experience.”

How is the full version planned to differ from the Early Access version?

“As far as the content of the Story Mode, there isn't much (if anything) to add. Based on community feedback, I would like to make small tweaks to some of the Story Mode levels and overworld to improve the entire Story Mode experience. Most of the artwork in the game is complete, but there are some things here and there that I'd like to add or adjust. The majority of what I'll be working on in Early Access are improvements to the user interface and adding in extra goodies to make the world of The True Slime King feel more alive. And of course I'll be looking to squash all the bugs that pop up!”

What is the current state of the Early Access version?

“Throughout Early Access, you might encounter a few bugs, but for the most part, nearly everything in the game is in a complete form. That said, I'm very open to community feedback and will do what I can to improve the game experience for players throughout Early Access.
  • The Story Mode has 115 levels and a large overworld to explore with boss fights and cutscenes to weave you through the story of the Slime King.
  • The Level editor and quick play mode allow users to quickly build and play custom levels.

Will the game be priced differently during and after Early Access?

“As the game is nearly complete, I do not plan to change the price after Early Access.”

How are you planning on involving the Community in your development process?

“I want to hear the community's thoughts on where The True Slime King shines and where it can be improved upon so that as a developer I can help nudge the game closer and closer to being as awesome of an experience as possible. I'll be keeping an eye on the Steam Discussion forums, subreddit, facebook, and twitter for feedback on the game. Players can help mold the game by sharing what they like and dislike about the user interface, level design, graphics, and audio, as well as any ideas for new features or content.”

Changelog v1.1.4 - Mushroom Redesign

The biggest change to this path is in the mushrooms. The mushroom sprites in the game were a bit too benign/friendly looking, so I redesigned them to better convey to the player that they are dangerous.
Changes and additions:
  • Reworked mushroom sprites (black mushrooms, brown mushrooms, wall mushrooms, ceiling mushroom, round floating mushrooms) to better convey to the player that they are dangerous.
  • Black mushrooms and brown mushrooms now have an alternative sprite that will be automatically shown based on the x and y position of the mushrooms.
  • The achievement text now displays as white before the confetti displays, and then it turns to green once the confetti comes on screen.
  • Changed spear hitbox to better match sprite.
  • Added spears for all directions.
  • Made orange overworld access goo pile more orange and less yellow.
  • Updated breakable block sprite in level editor sidebar to match the actual breakable block sprites.
  • Reworked sprites for extender blocks.
  • Added extender blocks that go up and extender blocks that go left.
  • Reworked player push scripts to kill player rather than push player out of the way.

Bug fixes:
  • Fixed issue with button blocks sometimes not tiling in quick play.
  • Made achievement confetti particles persistent objects that doesn't disappear when changing rooms.
  • When selecting a new folder in quick play, the scroll height now gets reset to the top.

Known bugs:
  • Jumping on/off buttons quickly can sometimes not trigger the button.
  • The death splat doesn't work properly on buttons that are depressed.
  • The steam overlay leaves artifacts on the black bars that appear if the game window is a different aspect ratio than the game camera.
