Ultra Alien Escape is a reskin of the original Super Mario Bros. game. It follows a little alien who pilots a UFO while trying to flee from planet Earth and make it back to outer space. Players use the arrow keys to move, jump, and avoid obstacles. Various power-ups are scattered throughout the levels and aid the UFO in making it closer to the final portal that takes them home. The player must also keep an eye on the UFO's fuel levels and collect fuel cans and fuel boosts in order to stay afloat and navigate the dangers of Earth.
