It seems to work and play well. I didn't work out what the blaster was for. I felt like I was just walking around nameless corridors. In the end I assumed the exit was not literal and just 'exited' the game :-)
The Sci-Fi Worlds pack is huge, so it would've been nice to have had some interesting things in the hallways to see. I've not used Tessera but I know setting up WFC algo tools can be a frustrating time-grab, esp the first time round. Still, +1 for getting it to be different on each playthrough.

The blaster is there to add a false sense of security. The only 'exit' is death, but if you have a good flow going, you might be able to keep oxygen up indefinitely. The asset pack is pretty large, but it was hard to 'design' a lot of clutter.
Edit: Actually I'm using Sci-Fi Space, which is less huge. I accidentally wrote the wrong pack.
