What a funky soundtrack, and a great game as usual!
I've seen the idea of swapping properties in some other games, but your implementation and the choice of objects works really well. Level design is great, the difficulty seems to be on point: took me a few restarts so not too easy, but also not too hard.
If I had to criticise something, it would be the object choosing control: it worked decently but maybe it could use some tweaking (or be replaced with a mouse-based system).
Don't know what else to say, outstanding job!
