I start doing the challenge at Click here and it will take you to when I started doing your challenge. I really liked the rest of the map and, good job with that challenge.
QUANTUM CAVES OF DOOM
A downloadable map for Windows, macOS, and Linux
To find the challenge, go behind the Slime Science Labs and find the cave to the left of the pool. This map was tested with full Jetpack upgrades, it may not be possible without them.
This map requires downloading & installing the BetterBuild Mod before use.
