Interesting idea, this feels like a mish-mash of sidescroller and top down mechanics!
If you want to make this a puzzle game, i agree with the other comment, you should slow down the blocks.
if you want to make this a momentum platformer (which could also be cool) in which the player goes fast with the blocks, you should lean into that and remove the one-room camera system.
At one point i got softlocked because a block got on the ceiling but i could restart :)
nice entry, i was pleasantly suprised by the main mechanic!
