good game
this game isnt easy once you get the tower nice and high which is awesome. however the controlls annoyed me. next time perhaps add a pause menue? also (as it seems to be the in thing these days) the addition on achievements may be fun. ie at 500m tall an achievement is awarded. might i also suggest that being able to spawn bricks inside eachother is annoying as it can knock down your tower, might wanna take that option away.
but overall this game is pretty good cant wait to see if you make a sequil
