This doesn't look like much but I feel the core mechanics are almost there. I think I could even make it for the compo.

Concept is pretty simple : you have to gather ressources to build your way out of a spaceship. Ressources are gathered from the environment BUT you get fewer and fewer ressources from the things you build there you might run out of space to move while the litteral space is out there to get you.

Also your jetpack is using the same ressource, there might be blackholes and all those lovely things.

I still have a bit more things to put in (tiles building, black holes and some funky objects) and I'll be able to focus on level design and art things. But first, some sleep.

(gif is a wee bit faster than actual gameplay, dunno why)
