I know I already made like 2 jokes about this being "Super Paper Mario 2" concept, but this is genuinely a really cool idea of switching between 2D, 2.5D, 3D and... you-know-what-else, ha ha. For a gamejam project, the puzzles were really cool, they made me stop and think a bit, and the ending part (not gonna spoil it) was also amazing!
Good luck with your submission, Krias! Meow!
