Hey, thanks for your feedback. I just released v1.2 of the game which should massively improve the performance for those having issues. I'd really appreciate it if you would take another look :)
Thanks
I played the v1.2 and it worked! I like the kind of realistic controlling of the ship in space, the sounds and feeling when I was in the shadows and the countdown made me really scared lol. I didn't find the moon, I'd suggest for you to add something to make it easier to find like some coordinates or elements on the stones that leaves traces to indicate something, depending on the target audience. The design was really cool, good job with your engine!
