Solid idea, fun puzzling, and great voice acting.
However much of the platforming after the first part of the game becomes very frustrating. Jumping up next to things makes you barely jump at all.
Jumping on coreium blocks is next to impossible, especially since you can't modify your speed, and you always seem to slip off.
The smallest ledges can't be walked up to, so you have to try and jump onto them, with how slippery jumping is, this just complicates things.
Honestly really cool, I just wanted to share my frustrations with the platforming and physics in the game, so in the future you can hopefully improve on these things!
Keep up the good work and I hope to see more cool stuff from ya in the future.
