ok, just some hints. Add music. Improve the character look. change the background from white. Add a story. Change the title and the pic. Improve some of your lazy graphics, such as that red triangle boomerang... button... thing. You came far enough to code the game, how 'bout you take it all the way, huh?
ok. I'm going through a rather intense course of digipen on the side of school that lasts about and hour each day. Once i am done with this, i will come back and call you names for being lazy. However, i have not developed a game, so i do not know how it is like. So, until then, go spend some time making some good games.
