I like the concept behind this game; the 7Day FPS 2020 jam provided Burgerpunk, which reminded me of this and I loved dearly.
It feels like there's a couple things that work against the player here. I had a lot of trouble with the recipes angle; there's no reference in-game as to what recipes need what, and with extremely limited time between waves to make recipes it becomes difficult to try and make some things on the fly. The actual recipe process seems to be particularly finnicky as well--tossing in a bread, cheese, and bread rejects the entire thing, rather than ejecting out grilled cheese and bread.
As much as I wanted to like it, trying to maneuver around an arena to only pick up what I need and keeping track of recipes and what I've picked up while managing ammo and health was a bit too much for me to keep track of. I didn't get too far in the game, though I'll probably try it out again!
Also, is there a reason it needs access to the internet? My firewall picked it up and blocked it, but there doesn't seem to be any online features in the game.
