The spell crafting system is really fun! I found two potent spell combinations fairly early on and cruised through the game by stacking magic regen and dumping everything into those two spells, and then keeping a self-healing spell for good measure. So I didn't innovate a whole lot with the system, but it's very cool nonetheless.
The Touch effect has a really short range, and it seems that your player's hitbox is the entire sprite instead of where the feet of the player would be. So enemies coming in from the top could damage you before they'd get hit by the Touch spell, which also has very, very short range.
Nonetheless, by the end of the game, I was an unstoppable beast, evoking the best parts of a Vampire Survivors-like game. Fun game!
