Okay, at first I didn't think I understood it, but I'm so glad I stuck with it!
This game is crazy fun, and the concept of continuing your run or locking it in for the leaderboard is really unique. I had a blast figuring out how to play - the only negative thing I can say about this game is the lack of sound effects (unless it has audio and for some reason it wasn't working for me?). Some good sound design on top of the already outstanding visuals would make this darn near perfect.
Awesome work!
P.S. As I write this, I have the #1 spot on the leaderboard :)
