Thank you so much for playing my silly game!! And doubly so for telling me your thoughts!!!
Yep, you're 100% on the mark for thinking he was the yandere. I'm unsure if it was clear, but at the decision where he prompted the player to return to the dorms, he was testing her - and taking the bait results in missing his route. He's a very dedicated yan :^)
I'm really glad you say the game is good! This game was a little rushed, admittedly, and mostly hinges on playing tropes from villainess media, so to hear that regardless of it makes me happy. If I had more time or was making this seriously rather than for a joke game jam, I think developing the characters further would have been fun. Alas (currently pre-occupied with other actual otome projects so I most likely won't expand this one)
Clarence's ball ending is my favourite, personally :D but yeah, for a guy that the MC literally refers to as 'fuckface', yeah... that checks out!
