Looks cool, but I haven't got anyone to play with. I'll still make some observations tho, first up is that the resolution doesn't seem to be correct, and I can't see the edges of the screen, and the players are not visible from the start. It is also hard to tell which way you're facing, as the front of the ship looks very similar to the back of the ship. I'm also not sure why you'd use the teleporters, they're often close together and seem a bit unnecessary to use. Perhaps there could be some interesting mechanics arising from this, like perhaps you get a speed boost by going into the portal, or maybe there could be a lot more portals and portals are almost a hazard?
I can't say that I actually played, so no comment on that, but hopefully these little nitpicks can help with polish =)
I also need to mention how nice the spacey graphics are, and the neat ambient music, nice mood!
