Super fun mechanic, I can't wait to see where you take this game in the future!

Good game mechanic but I've encountered a few bugs that stopped me from actually playing:

• The obstacles were sometimes the same color as the background which makes them invisible. 

• The terrain behaved the same as the obstacles 

• I couldn't play again after the first game over screen, no matter how many times I refreshed the browser window. 

If you chose to update after the voting is over, you can have a nice little fun game there. Rock on!

Sometimes obstacle cames in the same color of background and is impossible to see. Nice game, just need more polishing.

Nice game mechanic and artwork! I love how you change the color from white to black, it's looks smooth, but I think you should find the sound effect for your game. i will increase the dynamic of the game.
