The game is literally a sandbox, you don't have to follow a specific route to enjoy the game, you're on your own on this giant island.
Some may find content inside this game amoral, disgusting even, but these types of fetishes do exist, there's nothing we can do about it, but at least most of the people like us keeps it only in fiction.
For the game, there's lots of content to explore, starting with trying to figure out what the hell to do, cuz you don't really have a proper guide in the game, but it never bothered me this much.
Continue with storyline, story is smth-smth, i never actually properly read it, cuz was playing a JP version without translation and since this game finally came to Steam, and the on F95, i can finally write a review.
The Unity engine maybe a miss with suchgame, a lot of users having troubles, but for me, navigation from keyboard to click-to-walk/interact never caused me any butthurts.
The main thing i like this game is creativity, it may be focused around gore, but people have proved to be quite an artists with this game, not only i seen recreations of certain characters and places, but seen amazingly well-done bases, decorations and imitations.
Your only limit is game's engine at this point, cuz cheat codes are open for everyone and not locked under some Patreon bullshit, have fun playing.
