A fun game with a nice crafting concept! There was a great variety, and it was exciting to see what each newly crafted spell would do.
I wonder if I missed it, but is there a way to aim spells further away from you? I kept dying by casting spells too close to myself haha, so I think it would be handy to have a visual indicator of where my spell would land while I was aiming.
The other thing I noticed is that pressing "Esc" seems to quit back to the main menu rather than exiting from the cauldron/spellbook, but pressing "E" works fine.
Overall, I found it enjoyable and interesting! :)
