thanks for your comment. I had a lot of feedback during development asking to implement a way to stack/store items, but for me it's part of the theme ^^. In most RPG games, the player is always selling lots of crap to every shopkeeper, and it has no consequences. I wanted to show kind of a "behind the scene" of what the shopkeeper has to endure everyday.
I may improve that for a post-jam version, I'll put that on my list.
yeah, a last minute bug with the potion can make the last level possible without the last craft :/
