You might need to double click start. Controls are A and D for left and right, and S to go down, but not hitting S will make you always go up. Hitting right arrow will make you deflate, (explained later in game) and left will change you back. Hitting T will show your time. The story is that an evil dragon is stealing balloons from wizard kids, and you need to get to them to make them happy. After beating the boss is still a work in progress so ignore it for now, also the high score is stupid high, will fix that.
This is a project by Doublewhip, but I added new levels. Check out the original before playing this one.
