You used gold and a bit of a reverse on the golden rule... revenge or stealing back. So... you're doing to them what they did to you. But the golden rule is really more about treating others how you want to be treated. So that's like wanting them to steal the gold from you all over again LOL
A few things I noticed: If you hit golden luckies from underneath it stops your body like hitting a ceiling. I also think it would've been better to use something more noticeably different than bronze. It made it too easy to accidentally pick one up thinking it was gold. The little sparkle was hard to notice as you're running. It looked great on the last scene where you fight the two sneaks though since the sun glinted off them. Maybe just changing the lighting in the first scene would make it more obvious which is which :) Jump was mapped very odd, most games use A to jump. When possible you should stick to convention so it is not confusing and so it is more comfortable. It felt very odd to jump with Y. I wish there were a crouch. I hit the last bronze lucky with my feet a bunch of times losing all my gold and having to start over. Also, one of the sneaks hit me with his foot as he was falling down dead and I took damage. Your music is nice but a little overwhelming. It seems very "epic" like it would play during a big scene in a large movie like lord of the rings or something. I would have liked something softer and subtler that can run constantly in the background and not draw your attention too much.
Good job!
