It's a fun little game! It really focuses on BDSM fetish, torture is kept in reasonable range, the example pictures give good perspective on what's in the game.
Plot: You're playing as the captured girl who has to withstand 3 days of torture. To do so, you have to explore the dungeon between torture sessions. MTL is OK, I didn't find any problem following plot nor any scenes. There are few lines that aren't translated, some text is actually picture.
Gameplay: It's entirely on the map, avoid being hit and in stealth missions avoid being seen. In boss battle, hit enemy until done. There are also some simple puzzles, some of which can be skipped.
Content: Top notch! In the dungeon there are a lot of sprites of bound and suffering girls, sound is also good, combination of those do wonders to immersion. If enemies hit or see you in stealth mission, there's a sprite.
Overall: I gave 5/5, it hit my fetishes and provided nice amount of variety of BDSM scenes.
