This had a lot of solid spell cards but the visuals need a lot of work to make them stand out more. The player shots were way too prevalent, and a lot of the bullet colors (the lighter yellow-ish ones especially) didn't pop enough from the background, so if you weren't paying strong attention to your player's hitbox you're basically guaranteed to trip up. Try and focus on contrast between the environment/player and the enemy bullets. Also as far as spell cards go they were mostly good but with a couple of unfair moments. Her second card fires homing bullets at you before you can even think of why and basically always kills me when I first get to it, consider a cooldown or warning before anything that could potentially smite the player so fast. And her rainbow V formation attack became too packed together to actually dodge sometimes afaik.
Anyway, this was a pretty solid one that got pegged down a bit by some stuff that's probably easily fixable, which during game jams happens a lot so nice work!
