Really cool idea! Reminds me of a similar game I used to play when I was little where you stacked cats. It's really hard to tell where the houses will land, especially once you get a bit higher, maybe some sort of indicator besides the shadow could help. Music is awesome, but doesn't loop if you stay on the death screen for too long (that's just a box to tick off in your audio source component). This is more personal preference but I feel like the boxes could be a bit less bouncy. Also, the best strategy is to do literally nothing and pray that you don't get a L-piece because everything balances perfectly. Congrats on finishing! (Highscore of 26)
