Protonaut

How to Play:

The premise of the game is fairly simple: you are a small character (presumably the Protonaut), tasked with collecting all of the gaseous elements in each level. To do this, you have the standard techniques of running ([left] and [right] arrow keys), jumping (the [Z] key), as well as firing a small projectile (the [X] key, with the [up] and [down] arrow keys to aim). Also in your arsenal are the wall-jump and the wall-hop, which allow you to explore places that would otherwise be out of reach. With these 5 meager techniques, you will soon be gathering Oxygens, shooting down Nitrogens, and jumping up for Hydrogens.
