Helium Boy is a decent platformer that is based on figuring out how to overcome obstacles by using your balloons correctly. You can hold up to two at any time, or release all of the balloons currently inflated by pressing the C key.

Areas too high to reach with a basic jump can be accessed by repeatedly pressing the Z key with at least one balloon equipped. Prepare one quickly by pressing the X key.
