This is great, very polished gameplay, fun and unique puzzle mechanic. It was challenging but solvable after a few tries. I really enjoyed the vibes here, with the SWEET a capella level music and the simple but stylized artistic design. The simple shapes you used with the greyscale color scheme works really well together to make a cohesive vibe. Also your intro is surprisingly cinematic for 4 blocks! Well done, one of the best in the jam!
