Love the graphic profile and palette, and the bounce to all the movements -- it feels very visually polished. The mechanics are nicely responsive and make it fun to move around in the world you've created. Nice!
I played it until the final (?) round, where I pushed on the button with the trophy symbol and "???" below, and it caused my browser (iOS/Firefox) to crash (I tried this twice, same result both times). Some other feedback that I hope is helpful: when I started, the map launched me with the second stage selected. I pushed left to go to the first stage and completed it. It then sent me back to the map with the third stage selected. I pushed left to do the second stage, completed it, it sent me to the fourth stage on the map, etc. etc., so perhaps a stage variable needs to be decremented by 1?
Would be fun to play more -- nice work on this!
