I loved the idea of walking inside the ship and having to do space walks for maintenance. I felt like a mini star-citizen. The controls were very tight, and the graphics were nice! Nice job!
What I found annoying was how fast the status degraded and how abruptly the "game over" was if any of the statuses got to zero. I wish the thruster would prevent your ship from moving instead of a straight game over. Also, having some alerts like "low on oxygen" would be nice.
The idea of having in-game UI/screens for coordinates and ship status is impractical. I wish these were toggled HUDs. (I expect a space explorer to have some sort of head-mounted display :P)
(Thank you for making this available on Linux :))
