As far as top-down bullet hells go, this one was a mixed bag for me as far as design decisions. On one hand, I really liked the spell mechanic and only being able to have two slots. Forcing the player to decide whether they wanted to replace one of their valuable slots for a spell they don't know what it will do was interesting.
On the other hand, the player's basic 'left mouse' attack I didn't really enjoy. Spam clicking to attack is a valid way of doing it, but it's not really my preference. However the main flaw with the attack was the lack of feedback in terms of what I hit and for how much damage. Yes, I know there were health bars but you cannot forget to neglect sound design!
Additionally, the bat enemies I perhaps just wasn't understanding, but it seemed like they would sometimes shoot out small projectiles in a ring around them? This is fine, but if those are bullets to be dodged like in a bullet hell then I think they should probably be bigger. I somehow went from 20 to 11 health without even noticing, which as a player I found confusing.
Thank you for submitting! I look forward to seeing future creations in other jams.
