This is a fast paced platformer that it may take some time to get used to. You have 15 seconds to get to the green dot. If time runs out or you hit the yellow, you fail. if you get to the end under 15 seconds, you succeed. Have fun! double click the flag. The fail sign will stay otherwise, and nothing will work.
Thx to jromagnoli for the engine. It takes me 12 seconds.
