It's really difficult to find good quality foley sounds, especially ones without super restrictive or cryptic licenses that would make even a lawyer sweat and/or an absurd price tag. TomMusic to the rescue! Thanks for these simply incredible sounds, seriously.
If you're looking to update it in the future (fingers crossed), some pick up sound effects for collecting items like weapons, armor, keys, and a simple generic one, which could be used for any item, would go a long way. It is possible to use the inventory open sound, but that classic "pick up item" sound with the backpack opening? chefs kiss.
Anyway, thanks again and excellent work!
