Well I managed to get above 400 seconds, and it seems I could be doing it forever XD. Having the 4 systems running was difficult, but once I decided to lost Containment, it didn't affected me and sustaining 3 systems was practically impossible to fail.
That being said, I think the idea is pretty cool. I would expect to see a minigame like this in a horror game like Dead Space, trying your best too keep the systems running for a given time with increased difficulty. The ambience is pretty cool, the lighting is great and looks nice even though only using basic 3D shapes, which is much more impressive managing to do something like that with a basic setup.
I would have loved to see more effects, for example losing a shield or life support gets your crew or your ship destroyed, but containment and power did not affected the gameplay at all.
With some changes this would be a great puzzle for any big game, nice job :)
