Thanks for leaving such detailed feedback! I agree on the bottom wall. If expanded, game would go in the ridiculous build direction with upgrades, you can already achieve some pretty broken stuff with rifle bullets, shotgun muzzle, burst module but I want there to be more. Health in the shop would be a massive QOL addition, perhaps if we made it so the shop doesn't close after you leave that would be nice. "It's broken" was the gun starting in a weak state, and "Through the teeth" was going to be the shopkeeper ending up being the final boss. I ended up scrapping that as gameplay more important. Again thanks for writing such a thought out message.
