Underground is a 2.1 fanmade level created by AbstractDark.
The level starts off with a medium cube with tricky timing. Next is a robot which light taps (or clicks) need to be perfomed. After is a mini ship with spikes everywhere. The player needs to try to avoid these. Next is the spider. Next is a very short cube. The player needs to jump over the spike and use the black orb. That will make the player land on a red pad. The next spider needs very crucial timing. Then there's a ball with tricky timing, followed by a UFO constantly switching size and gravity. A ship with good skill needed followed by a dual cube with tricky timings. An upside-down wave followed by ship. A cube is next needing not so much skill but timing is hard. Then the player enters boss fight. A spider fighting monster bats reintroduced in the level. After that, a wave with lots of skill is needed. Finally, a ship with fireballs and columns colliding together. If completed, the text "Thanks for playing" will appear.
