I really like the concept of this game and the multiplier score; unfortunately, the game is significantly impacted by the collision of the paddle. The edge of the paddle seems not to exist, squares look like they pass through if you hit them from the side. Also, I don't know if others' computers have this problem but every once in awhile there's a lag spike and a square can pass right through the paddle. I think that this is a really great game that could easily be a 4-5 star game but I think that the collision needs improvement.
