PSP homebrew developer Helius - who tipped us off - and the rest of the Geardome site crew have just released their game for the PSP, titled Ozone. This game will put players behind the controls of a gas molecule as they race against time to collect blue gems before they shrink into nothing. Each stage carries multiple features, such as power-ups, traps, and enemies.

Ozone for the PSP used to be labelled as Hydrium - the latter name is for the game's Windows (freeware) version. This game is not to be confused with Hg: Hydrium by Sony Computer Entertainment, which is the Japanese name for Ignition Entertainment's Mercury (2005). Hydrium (according to Geodome) is the winner of the Best Design category for the ArtFutura 2005 awards.

Ozone's gameplay controls and instructions should be available in the file readme - make sure to go through that for further details. The dev team's site is also available via source link, in case you want to drop by to say thanks.
