a nice minimalistic style and i think the concept has a a ton of potential, i did have a few issues tho.
mainly i felt it was a bit annoying that the focus of your controls didnt reset back to the little cubes upon death but idk if this is a bigger problem for higher levels (only got to lvl 11).
also i'm sure you already know this but u can rotate the level while your little cube is falling which basically breaks the puzzles. the cheat would prob make a decently fun game of it's own tho lol
