I thought it was really good and polished feeling. I would have liked the upgrades to be a little cheaper or there being some cost to going in and out of the den cause I found it easier to just do quick short trips rather than invest in the upgrades. Either way I thought the loop was very well implemented. I thought the art especially the crafting menus were quite charming. I think that if you were interested in continuing this project it would be very fun with some more fleshed out progression and maybe some story elements. Either way I really enjoyed playing it.
