A decent game, though it could have benefited from more challenging enemies (e.g. that shoot projectiles/magic bullets/whatever towards you at least) and the controls for setting the aiming of the fireball was confusing to me (looks like only holding the virtual joystick on the right with the LMB (which seems more intended and natural for mobile, but feels weird on PC).
Also no audio, at least some audio (even just sound effects) would have been nice here.
