I like this dynamic crafting mechanic and I think it has great potential. A little qol change that would probably do wonder is to integrate the crafting menu and inventory on a persistent UI on the screen so the player doesn't have to constantly tab in and out of it. I would say that even with the duplication glitch, enemies still take a tad too long to kill. Some balancing might be needed. But still, it's nicely done for a jam project in just 3 days.
