I havent played it yet, but just looking at some comments as the game looks fairly new, I actually realy like the concept the MC isnt powerful but can "make" his girls powerful or as his weapons. Hes seen more like the commander, That works great for me. but the way you describe it here, its as if its the concept Friendship is power!. And on Karma, you are saying if you wanna play as a bad boy, you'll just get game overs ? or is it if you keep making the "obviously" bad choices leading to terrible consequences, then yeah, it will end in game over ?
But I like the idea you going to go hardcore, with the corruption and Ahego tags ^_~ Could be quite spicy
