Easy way to win:
The player is on the very top :D :D :D
Nice little game. I like that the levels are counted in binary.
Score is not working and the window cannot be resized.

They start coming from the top/bottom as well starting level 6 and shoot sideways, so that wouldn't get you too far. I didn't actually end up adding any bounds checks at all for the player though, so you could just go way outside the map itself. Shame the score is not working, it should increase every time you kill one of the enemies. Thanks for giving it a try anyways.
