Really fantastic entry! Lots of fun and high energy.
Usually when I see games with such pretty graphics they fail to deliver on the juice and feel. NOT HERE! you nailed it, it felt great to smack them enemies and the fireball traveled so fast you could really feel the impact. Very fantastic.
Now while the game did feel great the attack speed did feel off at times, it was fast but you would be stuck in it for a while, I think it would be better if the anticipation took up the animation time, then the swing was the interruptible bit at the end. then it would add to the impact rather than feel off. but tbh I adapted to that eventually.
I think there should definitely be more of a clear sign that there is a Damage over time effect on you, It adds alot to the game to have it since it makes you die more often, and the dying mechanic is very interesting and fun! buuut I just thought that the hitboxes were being jank for a while before I realized haha.
Last bit of feedback is a minor nitpick / pace thing. It would be very nice if there was a instant revive button, or if the circle instantly full closed once you got all available pickups while dead. Feels alot of time is wasted standing around waiting for the circle to close after you pick up everything.
Thats my feedback, but let it be clear, your game was fun, beautiful, interesting designs, and had pleasant audio.
Serious congrats on making something so cool!
