Real cool use of splitting and joining mechanic. Puzzles were smartly laid out, even ramping up in difficulty as I progressed. Models look cute and I really like their animations as well.
Not sure if it was a feature, but one time I had a slime stick on the wall, moving like a beyblade. I think it was the level where you need the weight of 5 slimes, and the first slime is on a platform. I guess the slopes on the wall made it possible for the slime to walk onto. Might be something you want to look into, but really it wasn't a big deal and it can pass off as a feature in my opinion.
Great work on this one, I enjoyed the experience! 😄
