This is a really good game.
They are a few bugs though. If you land up having low health and the screen goes red it's REALLY red. I would either make it flash or make it less red. Also it stays red the rest of the game.
It also gets a little laggy when you use the time bubble sometimes.
It also feels like the bullets go from nice and slow to really hard to dodge because they are so quick, very quickly.
Other than that I think this is a amazing game. Just needs a bit more work
Good luck soldier!!!
