Nicee, the game hooks you and make you want to increase your high score naturally, so that’s a good sign. Currently, my high score is 35.
I just think maybe it needs a little more adjustment to the difficulty so you have more time to react when enemies come from the bottom of the screen at high velocity. It could be something like the camera being a little further back, or the enemies slowing down after they hit you (I think this one is pretty common in games like this).
Congrats on your game! ^^
