Very cool game! Just one thing I noticed: when I chose the bigger power upgrade, I couldn’t shoot near a wall because the fireball kept hitting it. I’m not sure if it’s supposed to be like that.
Quick follow up, I’ve mostly fixed this bug, or at the very least it shouldn’t hit the wall if you’re aiming away from it (aiming too parallel might, depending on the size, I’ll say that’s expected and a downside for having a bigger more unwieldy projectile).
