Oh my goodness, this is such a cool and clever idea! :D Feels like one of the only falling block games I I've ever played where you wanna intentionally make holes, and it's definitely taking a bit to get used to such, especially the 2x2 Wormholes (but in a fun way)... ;u;
Good music and nice visual style as well, I keep wanting to imagine that this is a Bit Generations game or something, heheh!
