This is a very ambitious project, that seems to be well on its way to be realized. Unfortunately there are many bugs and issues that still remain to be solved. Others have pointed out many of them, but one I haven't seen here is that dropping a item while in crafting menu will cause its sprite to remain interactible and its resources inaccessible in the middle of the menu until you leave it. When I handled the recipe book this way, my game crashed. Congratulations on completing a game for your first game jam!
