I had no idea how to play this, my character just started flipping in place a bunch of times for no reason and then when I did start moving I felt to the bottom of the screen and got stuck there. In game there was no information on what was supposed to happen, or the goal. When I ran into people nothing happened, when I jumped over people nothing happened so it was very hard to figure out what to do.
Well done on making your first game, you did well to get it finished. With a lot of work this could be good, also think about how you are presenting your game as the bright green game page is really obnoxious.
