cool game! i played it three times because i found that you can pick up blocks at the same time you jump, which is really fun, although probably unintended lol
hitting enemies feels a bit off, and you can soft lock yourself if you can't put down a block on the last section, but other than that the controls feel good imo
personally i liked the art, although to me the colors looked a bit washed out (i guess due to all the colors being the same saturation) which is fine, but some colors look out of place like the cyan of the buttons and doors. if you want to improve at color i'd heavily suggest using color pallets from lospec as training wheels of sorts, i used my favorite color pallet for this jam, they are quite useful!
