Love the visuals especially the music. A really good combination of the jam's two themes.
It was disappointing when I couldn't combine two electricity runes, since I was able to combine two of the first rune.
I'm not sure how different ratios affected weapons. Maybe damage numbers would help to show the difference?
I wish there was some visual indicator when you took damage. A sprite change, a screenflash, something.
This is 99% me being dumb, but I had a hard time figuring out how to close the crafting menu :(
