IT WORKS!
Nice game, the intro is cool
It's really annoying to get hit by a fireball when you're clearly not touching it. I know you might think of something like the heat radiating through the air a little, but it's currently quite impractical to gauge whether you're gonna get hit or not. Another issue is the player sticking to the walls on the side of the screen. To fix that, add a physics material with friction turned off to either the player or the walls of the screen
Jumping often worked fine, however landing quickly becomes an issue, often times having no choice but to take a hit. The player character is really floaty, which is fine with how it makes you have to go left and right a lot in the air as you're tracing the movements of your surrounding fireballs, but when landing you don't have many choices left and when jumping then place where you'll have to land isn't even in view yet. If you could somehow fall faster at will that'd fix it, or if only the balls of your character could take damage and the cone can delete the ice cream, that'd fix it too as now landing is effortless. There's many more ways to do it.
The coins definetely help elevate the game a bit. It let's the player decide which coins are worth going for, and which aren't. Overall the game definetely feels like a game so well done, Ben!
(PS. I don't actually know your name, but it's probably Ben)
