The difficulty ramps up pretty quickly until you get to the 'shooting gallery', at which point it shoots up into the stratosphere. I can see what your intent is, but it's not all that fun to dodge bullets and run away from enemies.
Thank you for the feedback! I really need to make it a bit easier.
I made the phase to get the gun easier if you want to check out! (I was going to do that after the jam but i got too many comments for the level)
