just click space and jump and arrow keys to move. please note that if you touch the right edge then the arrow keys will become inverted. touch the edge to put them back to normal. if you touch the left side then it will remain normal.
The third game in the Jump! series. if there are bugs or things you want improved post them in the comments. in due course I will be making a Jump! 4 including most of the upgrades I think worthy in the comments. in the meantime, enjoy my new game!
