Thanks! I wanted to make level 2 more difficult than level 1, but it's a bit too much now. Probably because of the bullet speed and not being able to see bullets, especially the targets in the back are difficult to hit because of this.
Probably should've tested if the lose screen in level 3 worked as well. Didn't have a lot of time left, so I forgot. Should keep that in mind next time.
I'm gonna try to get somebody else to test the game before submitting it next time because they'll notice problems that I won't see since I've been looking at and developing the game constantly.
