Reminds me of Tricky Towers.

love it. simple and fun
Ahh a classic!
Super interesting concept, and very addictive too!
Good game, but at the start it really just depends on luck. You could get a block that ends up curved and the other blocks will slide off and into the void. It can happen at any point in the game, not just the start. This is the only complaint I have. Otherwise, good concept, good gameplay.
