This was really well executed! I love the minimalist aesthetic and the way the tiles come up to meet you at the start of every level. I would have like to see more mechanics slowly introduced, but I know how the time crunch can get. As-is this is a super calm, low-stress puzzler.
(P.S. We made a really similar game, but took the feel of it in a very different direction. Cool to see this take on it!)
