• Space-themed transport
  
• Debug building
  
• Ten levels
  
• and so much more!
  

Notes: Play on 1.12.2/1.12.1/1.12
DO NOT CHEAT! I have seen people's videos on this (I uploaded it to minecraftmaps a few weeks ago) and seen people cheat on the "Hidden Fire" and "Shooting Stars" levels. THEY ARE NOT IMPOSSIBLE.
If you spawn outside, walk around until you find a blue building with an iron door. Enter that to start.
