Really well-executed and simple matching puzzle grid idea. Before I get into that, I gotta say, the music was fantastic and an absolute bop that fit the theme of the game. Props to you for making that in Bitwig. For the puzzle itself, I think the idea's effective - the appeal is that there's always residual pieces, so the challenge of the game comes from cleaning up your own mess from loose parts, in a way. The atypical configurations made this much less Tetris-like and more unique, by making it a little more complex to consider how to pair things together. I found the game took a little while to see my errors pile up to a point where I had to start being more conservative with my placement, but the increasing levels and time limit get there eventually with the pace. The end-game grades are fun to boot. For constructive criticism - the player buy-in to the matching can take a moment. Even though it's explained at the start, it does take a little bit to remember what's what - an tooltip or onscreen element to remind players somehow could help. Very well done and great game!
