As far as frustration with flying/shooting - the ships felt sluggish. Additionally, the POV is pretty zoomed in so there isn't a lot of time to notice an asteroid coming and move the guns and fire and actually destroy them before they hit you or fly by. While I was playing I think i only used the initial small ship (the one you crash with the astronauts) and the bigger ship you get second. I wound up restarting a few times and repeating with these ships because I flew too far up or over and didn't feel like trying to navigate my way back to land.
Also I hope this doesn't feel negative. If anything, what you have feels like a great foundation and I can see a clear path something really great... I always wind up having more constructive feedback in that sort of case. You all did a great job and I'm impressed you did this much so quickly.
