This idea is really cool! Really reminded me of the Mystery Dungeon Pokemon games lol. Once I got the mechanics and strategies down it got way more fun. I had a bit of issues getting anywhere in the beginning because I didn't get a single drop. Once I did get a drop it made the game much easier so maybe it's a bit too reliant on drops? If you don't have ammo or can't 1-shot enemies then you have to take damage and again, if you have no drops you have no heals either. I understand this is a 7 day project though. It'd be really cool to see a full release with an idea like this!
