Not bad! Just some suggestions though, I think you need to have a bigger variety of sounds, like some background music maybe. The sounds got a little too repetitive. I also think you should add more things in the game like more obstacles to overcome. I liked how the red blocks exploded more balls out when you hit them. It made things more interesting! Some more stuff like that would have been cool. One last thing, there was no ending to the game really, nothing happened once you passed all of the levels. Maybe try have the scores added up at the end, and if you wanted to take it a step further then add a leaderboard to rank the scores. All in all though it wasn't bad! Looking forward to see how you improve things in version 2 if you make it.
