click the blocks on the top to spawn them then hover over the block and press and hold the space bar when you want to drop the block let go of the space bar same with all the other blocks
there are a lot of bugs like 1 if your cursor goes of the block when you are holding it it will stop 2 if you are holding a block and your cursor touches a nother block the blocks will combine (try making block hybrids with it) 3 blocks look like they have a grid in them i will try to have all of these fixed i made this game in less than 1 hour
