Nice game, perhaps a bit too easy, beat it 2nd try with 2 different fireballs and basic attack. Also I think "deflect" is bad word for "Repulse" because it actually don't reflect projectiles, but just destroys them from what I've experienced.
You must be very skilled then! It's quite hard to balance a game for a jam as we did not want players to rage quitting because it's way too hard. But I understand the no challenge no fun spririt. Agreed with "Repulse".
