I found a bug. You can have sex with the waitress even if you don't have 500 gold, by just moving the menu cursor down to the blank space where the option would otherwise appear. Doing so gives you negative gold.
Also, just a small QoL change I'd suggest - make the enemy drops appear instantly, instead of having them appear after their corpse fades away. This makes it so that you can walk over enemies while killing them to instantly pick up the drops.
Also the voice gets annoying for every single kill, maybe have it play on a 25% chance?
