Interesting game! Nice idea with the fountain, a lot of bigger games could borrow it as a solution from situations when you just miss couple of coins!
Art is pleasant although I wish walking animation would look more like walking and not just wiggling. And footsteps SFX is kinds weird, it took time to understand what this boomy sound represents.
Game systems are good! There's some progression and some management, but I wish game had its own mouse cursor because I didn't know if it actually affects range of throw.
Good work.
