Threat from Outer Space

Made for the 3rd Mario Jams competition, where the theme was "Disaster."

After spotting a foreboding spacecraft hovering above the Mushroom Kingdom's airspace, there was only one man up to the task of dealing with it: Mario. Could it be aliens? Shroobs? Something even worse? Whatever it is, Mario has to prevent whatever disaster the UFO may bring.

The upper atmosphere above the Mushroom Kingdom conveniently contains a very linear path towards the UFO, with optional Red Coins for Mario to collect.
