V1.0 ---
A sci-fi themed hack consisting of 4 worlds with 16 levels in total. Mario has been erroneously teleported to an alien planet and needs to find his spaceship to get back home. The hack is of medium-hard difficulty and is mostly recommended to people who have already mastered the original SMB1. Some levels require you to go into the right pipe, walk through the right door, or hit the right vine to finish.

The concept for this hack dates to June 2017. Initially being nothing more than a graphical test created by Patty, it was reworked to be a proper hack starting in the Summer of 2020. In 2023 it received a massive upgrade in its music and coding, courtesy of StudsX. Most of the levels were done by Patty, with tweaks done by StudsX and Eden GT. 1-4 was designed by StudsX.

Levels:
*1-1 - Arrival at the Planet
*1-2 - Under the Surface
*1-3 - Island Hopping
*1-4 - The First Lair
*2-1 - Waterfront Stronghold
