Looks pretty polished and is fun. I didn't quite get how the minigame at the beginning works, but it's a nice addition to the game. It would be nice if you could also do more than just fight enemies during the main game, maybe collect some upgrades. It is possible to get very close to the top border of the screen, making it easy to run into enemies above the screen, I would adjust the camera scrolling. Overall a pretty cool game.
