The game is over 10 years old, it's from the era when people made ripped asset games for fun and not profit.
A lot of these types of games were on hongfire, but this is the only one that keeps chugging along and I'm honestly happy about that as I admire the dedication.
I don't like modern asset rip games but I enjoy this for the nostalgia and he has put a lot of work into it even as a hobby.
