Wow honestly, if you overhauled the visual design and fixed some of the bugs this would make a pretty fun mobile game! I actually played this more than most games I've tried thus far. Also, I noticed heavy slowdown and frame drops after a while. I think it might be due to the bullets not being destroyed off screen, and as a result the game is still keeping them in memory and rendering them offscreen.
I'm glad you liked my name suggestion, I appreciate you putting me in the credits even thought you didn't have to. Overall, a very fun game and I'm glad to have been able to play it.
