Press flag twice (Oranges might spawn if don't) Use the left and right arrow keys to make the balloon move left and right. Press the up arrow key to make the balloon go up faster. Press the down arrow key to make the balloon go down a little. Dodge the obstacles. There are sky divers, there is wind, there are clouds. (The clouds blind you because they're foggy). If you get hit, it will decrease your percent of air, shown right above the height at the top right corner. Once your at a height of 45000 feet, your balloon is in space (I know, 45000 feet isn't space). Your height is below the percent of air. In space, your balloon won't go up like it normally would. Because of gravity, you can move it in all directions now. Dodge the meteors that look like oranges. In space, also, your height variable went bye bye. Now it is "distance to Earth". Instead of only going up, now go left, right and up. To lose, right at the top corner is the percent of your air left. If it goes below 0, you lose.
None (Oh yeah, btw, this is probably one of my worst projects. I think it's boring and repetitive).
