The MC is a male. Just entered college/university. Halfway through the game he spies around campus and stumbles upon a cult like group in the school auditorium wearing robes, I can't remember if they had their faces covered or not but, standing in a circle on the stage. I remember a scene where the MC walks into a toilet and sees a person who was nervous about the whole situation, so the MC took advantage of that and knocked him out (I think) and steals his robe. He then walks into the auditorium waiting in line behind a guy and some dialogue exchanges. Eventually came MC's turn on the stage standing in a circle with other cult members. They bring out one or two girls onto the stage and the MC recognizes the girl(s) from his own campus and other members start bidding for them. This is where my memory gets shady but the MC maybe got caught by someone who recognized him or the guy in the toilet earlier woke up and walked onto the stage and created a bunch of attention eventually getting the MC caught. If I remembered, the game ended there because it was still in early development. The game was probably made with Ren'py, HTML or RPG Maker either one of those but most likely Ren'py. Unfortunately I don't remember any part of the title.
