I can't really say much more about it. It's from an era where hacks didn't need to be amazing to get a lot of praise, they merely needed to be of the "fullhack" variety. There is a lot of weird and bad gimmicks being used, poor save station placements, awkward visuals in a couple of areas, etc. There are many complaints to be had, but on the contrary there really aren't any positives to speak of, I for one don't have any that comes to mind.
If you want to see some weird gimmicks using engine quirks? Go right ahead.
Want to actually play something enjoyable? Look for another hack.
