It is brilliant for the short time span you had to make it in. The retro styling and everything is fantastic and very eye catching.
Only problem I have with it is that everything seems a little too complicated. I didn't completely get the sector map thing (maybe that's just me) and the weapon choices and everything seems a little sophisticated. But that could be just the thing some people fancy.
All-in-all, its unbelievable how you made such a beauty within a week.
Congrats!
