Great Breakout game!
I noticed when the paddle is out of the playfield the bottom of the paddle is not showing.
It might be fun to start with 4-5 power ups to collect like it is now and every few levels one power up gets replaced by a better (similar) one. E.g. instead of 2x 3x or 2 small paddles next to eachother with a small gap in between, instead of F missiles, instead of B big balls or explosive balls etc. This would give extra incentive to try to reach further.
With so much action in the playscreen I sometimes find it challenging to look away to the corner to see what level I'm at. Maybe you could alternate the Shkapang banners at the sides with the level number.
