Don't judge it by its graphics or its sound, but by its unique gameplay that it has to offer.
Graphics: By modern standers of techology, this is one of its draw backs. Artistically it's great, by all means, but it offers nothing new to the standards of amazing graphics.
Sound: There's not much to really listen out for. Everything is written in subtitles. There are noises from the "creatures" in the game, but nothing really stands out.
Value: Being that it is only $20, it offers a lot, but it also offers very little too. Seeing that the campaign is very short and it crashes pretty often.
Tilt: I've enjoyed the game, but as I said there are a few drawbacks. It's definately fun and original. This small budget game definately mocks the many big budget failures with in the last few years.
