NICE! Well done on making a shooter game!
I read through what other people said and i mostly agree with them. I liked that you couldn't just reload - you had to find a burger and grab it. I think that is the main mechanic here and the root of the game. Since that is the main mechanic that differentiates your game from other shooters you should make sure it feels good. Being able to get more ammo into the gun by consuming multiple burgers could have been good since i found myself trying to reload while i had 1-2 bullets and I was unable. If the mag could hold 16 and a burger gave 8 i think it would have made it better.
Also thank you for giving me an example solution to a problem that I'm currently struggling with. I always leave my game world as a plain and the player can just hop off. Horrible.
You gave the world a stomach around it and a logical way that the player dies when they fall off the platform. Great job!
