100th: Save Your Balloon Buddy

You love your balloon. He’s your best friend. But he’s hard to hold onto. In 100th, you must take him through the various levels without losing him or popping him. Luckily, there are several folks around who can help you get new balloons if you lose your first one. Note: See below game for instructions and tips, plus a video walkthrough.
To begin the game, click the area where it says “Click for focus,” and then press “X.”

Instructions: Use arrow keys to move and jump. Press Z to hold balloon (CTRL, Shift, and X also work). M key toggles music on and off. Hold the up key for higher jumps; you can jump higher when holding the balloon. Keep in mind that it’s easy for the balloon to slip from your fingers. Also, in this world, if you’re holding the balloon, you stay on the ground, but if you sit on top of it, you can float to higher levels.

100th is fairly short and not extremely difficult, although there are some secret extra challenges in the game that are pretty tough (for those who like that sort of thing). Earn extra bonus points if you make it to the end with the original balloon.
