you can make jokes about vaseline, but I think this looks pretty impressive for nearly decade old hardware specs. ever LOOK at PS360 specs? there's almost nothing there to work with by today's standards.
To be fair the game has a minimalist art style, a lot of retro looking things, with plain white lighting etc in most cases. I guess the bigger difference will be visible in later areas where the alien is rampaging and there's a lot of dynamic lighting etc going on.
Would love to see a comparison of those areas too.
