This game is really polished for a jam game, good work! It's a really good take on the theme as well. I like how many ways there are to complete each level. I would say, though, that some of the puzzles are too easy, as there is an overabundance of blocks to complete the level. Maybe there could be a "hard mode" option or something. Great game!
I also role-reversed a platformer but in a different way. If you have time, I'd love it if you tried it out!
