Fun little game! I liked the variety of different bondage components you could get. The hitboxes on taking items out of the box and the expedition crates is really finicky, though. A fix for that would improve things.
Also, I found a bug: putting a expedition crate into the box resets the number of items it's spawned, meaning you can get infinite uses out of any single expedition crate if you have the box. You'd be surprised how many times I've seen a bug like that in a game.
I feel like the sell prices on the tar pits stuff, and especially the mummy stuff, is a bit low for how expensive they are to get. It always felt lame when one of them popped up in my special order.
