I really respect what they've done here. First: it is completely unoriginal in every way I can think of, including the chop job that guy did on the music. BUT. Everything they've done looks (and sounds) high quality. So while they might not have an original thought in their heads, they executed everything really well, and that is worth just as much praise as an original idea :-)
Small developers are the only ones doing this genre. There are more space games out there and coming than the reader realizes. I say GOOD ON THEM!
