nice game with unique concept!
i enjoyed playing it
however, lmao, the spike in perceived difficulty in lvl3 is a whole shock.
i got stuck at level 10, so i can't review much about the levels afterwards, but the ones up to 10 were quite enjoyable once i got past lvl3.
if you want to continue developing this game, i suggest you add a couple of levels to help the player get comfortable with the mechanics of the game.
i would also recommend improving on your art.
picking a limited colour palette with hue shifting for your art is imo a good way to achieve something that looks solid.
the symbols you used conveyed their actions well, but for me they sometimes looked quite similar, partially because of how small they were (in windowed mode).
all in all, for 50 hours you got quite a unique puzzle game with an admirable amount of levels.
