As a test it seems okay. not sure what purpose the jump serves.

Decent game, for only a html test it's pretty good. However the style of the game you picked is already quite overdone as of late, as well as the fact that there is no defining feature or mechanics in your game. I'm not knocking on you or your game I just want to see you make better games in the future if you decide to make more in the future. Good luck developing!

For an experiment it is a decent try, I shall give you that. Lots of room for improvement.
