Nice game, I like juiciness and smooth player control, graphics and sounds are simple but nice. I'd say that it would be better with more balancing, like i realized at some point that it's absolutely not worth collecting coins unless they are rigth in the middle of the map, because you are risking be randomly attacked by an arrow with -1 heart that worth 50 coins. Collecting diamonds also not worth it as 1 heart = 5 diamonds, but it is the only goal we have, so we need to collect them. It also means that if you lose 1-2 hearts it's actually quicker to restart the game to restore it rather than trying to restore it by collecting diamonds. Also i'd suggest arraows to have a visual hint before they fire, this should improve this risk/reward problem and make the game more fun as a result. This is all just some suggestion, not a hard critique or something, i actually enjoyed playing the game!
