Very polished submission! I enjoyed the process of putting down bricks and seeing them squish together. I think there should be some incentive to place the blocks faster (I saw there is a bonus timer, but I never really cared to reach it). Kind of something like in tetris? Like maybe, if you don't move fast enough, the blocks will fall on their own? Just food for thought. Also, I love the sound effects.
Anyway I enjoyed this a lot and you did a great job!
Edit: Also, sometimes when I pressed my key, it would move 2 spaces or place 2 blocks instead of one at a time, which threw me off a bit.
