Thanks for the extensive feedback. These types of reviews are greatly appreciated.
I will try and implement a line for aiming after the jam is over. The enemy spawning was intentional because I thought the game would become too easy, but it just happened to be the exact opposite. I had initially implemented autofire, but continuously spamming fire made the game too easy to play so I removed it. I guess the best way to counter it would be limited ammo. And lastly for the collision glitches, that was fully on me because I saw them and I knew about them but just didn't have enough time to fix them.
Thanks a lot for the feedback once again. This was truly appreciated
