A few things I noticed:
-The screen moving gets stuck for a few moments at the right and left edges-Are you supposed to be able to place the blocks on top of each other?
-I found myself trying to place the blocks back were they are stored manually or the block storage would obscure block placement (lower opacity when hovering over for fix?)
-There was an instance where the robot made it, but trying again didn't, even though nothing changed
-Having switch modes be "space bar" instead of enter means you don't have to move your hand from WASD
