Putting the "play" button on an unplayable area is stupid ! Move your button elsewhere. And only 1 level is kinda boring... I'm sur you can do better for your next game.
We really need to respawn or at least put a floor under us and force us to return to the start (wouldn't be fun but better than reloading the page).
Some bugs but not a bad game. Work on it.
Check the game information.
