(edited my post before)
its a standalone game, where the graphics are kinda like on Mother (earthbound for the western world) everything is more cute.
it was intednded as a parody on the original but delivers some background information on the original one. its more lightheartet but definately worth playing. the fanmade translation is pretty good too. (it came out only on the jap market after snatcher)
give it a shot!!!! if you liked snatcher its really fun plus a good story
btw my avatar is from "snatcher" haahha
ingame:

nonetheless its still violent
to come back to the different snatcher versions:
the mcd version is stil my favourite, not just because I own it. I loooove the soundtrack and it definately sounds best on that one.
the game is is still pretty gory and the "sex tape" situation is still funny, hahaha
