It's a cool idea! Some more explanation would be in place. I didn't understand what most of the gun extensions actually do. The range extension I assume increase the range of the bullets, but the bullets would always go as far as I could see anyways. The bouncy, and penetriation extensions I have no idea what did. The most important thing seemed to be that they acted as protection, which was clever! When running out of bullets (and there's no more bullets to pick up) you are just stuck?

Ah, yes. Such is the way of the Game Jam. 😝
Ah, yes, I noticed shoving was possible. It should be explained somewhere though.
When you don't have enough time to put a proper UI and explanation in the game, you can always just write a small description of everything on the itch page after the deadline. :)
