I'm inclined to give this game 3 stars because of the bondage robot itself, but I'll give it 2 because of the abysmal gameplay, I was tired playing the game and almost fell asleep, it is that tedious.
Main Issue (Puzzle + Map)
The art's great, however the game itself is plagued with very boring gameplay mechanic. First of all the D100 system, if you are lucky you can skip almost everything, went into a key room with lockpick that skipped the first section of the game without knowing anything, sometimes its just frustrating because the hints are quite bad, its obvious in a bad way that it tells you something obvious but the labeling of the map is so poor it ends up not working properly. There's also a whole section of a game that just forces you to prematurely end the demo with no way to backtracking, the game autosaves also screws you over.
Compounded with the poor labeling above is the enemy density, holy hell this game has so much enemy, I have no clue why, if the game is meant to be puzzle focused, whats the point of 15 or so respawning enemy that populate every map for little reason. If a game is puzzle focused, reduce enemy density, if the game is combat focused, reduce map size and improve labeling of the map.
Combat and H stuff
Other than the bondage ray you get from passing out in the first room a few times, unremarkable, enemy attack or do some light grope, your horny goes up or HP goes down, horny reaches 100% you get stunned. That's all at least in the demo.
You spam attack until enemy die, your Hologun ray does the same dmg as your Attack so no point using it.
