It's definitely way too much work, it was my first time implementing a UI system like this even though I've used Godot's UI nodes before but never made them work together with textures like this. Out of all the individual systems or features, the crafting UI took me the most time to complete.
And thanks for the art compliment. I'm no proper artist but I did the art. I randomly started learning pixel art to make games a couple years back and it has improved to this over time.
