I love the gameplay. It's deceptively simple but it takes a lot of skill after a few levels. The art and music also complement it wonderfully.
I saw this game coming to life during GGJ and I must say the end result looks really nice! I love the multiple endings and Luis's music fits perfectly!
I really like the mechanics, they're very original. I think, though, that the difficulty curve can become kinda flat for skilled people. Maybe you can add a countdown timer. Each coin adds a few seconds. You start with a lot of spare seconds so its easy to avoid risky coins at first, but when you start running low on time you also start being less careful.
