Not a bad start, I like the vib, but I had genuinly no idea what I was doing, I put down a few block's then the game stopped letting me place them...
I know it a bit of a work around, maybe just push for some descriptions of the tile sets.
also not sure about the block placing itself, as the fact it was hovering above seems like a weird design choice, but maybe I just don't get it.
All in all keep up the good work :3
