I got no clue if this would count as something you’d be into, but I’ve been having fun with Skyblock Zero on Luanti.

Idon’t know how quickly you could finish it considering I play purposefully inefficiently, but it’s a space themed with a quest line to follow where the only limited resource is your time. Spawn on a voxel, keep clicking to gain resources, and build out from there. So far one of my only gripes is storage in the game is only drawers instead of chests, so I constantly have machines and my inventory filled.
