Just played through the entire game, and I had a complete blast playing through it! One of my favorite hentai games of all time. The only negative if you even wanna call it that is that the endings were a bit of a whimper instead of the explosion I expected but that's totally fine.
(Also, how do you get Ending C? All the other 4 endings were variation of how you do your end task(s) but I couldn't decipher C at all, maybe something to do with reputation with one of the factions?... )
Hey there! Thanks for the praise, I'm glad you like the game! :) Yeah, I know that I usually like to wrap endings too quickly, but it is noted, I'll think of what to do with it. :)
For ending C you need to max the FCK rep and win their idol competition, after you sign the contract with an executive, and after you defeat the Logan - you'll get the ending!
