The cuck ending really implies or at least makes me think the guy the MC is getting cucked by is Gideon.
Either way I dont think im going to be following this game anymore for various reasons.
1. The cuck ending implies mabel has been fucking the dude (probably Gideon) for ages and is addicted to his dick, so its cannon we're basically cucked throughout the whole game already since its game canon she's been fucking him since before the game plot starts.
2. Mabel says "im glad dipper didnt show you that other pic of us, that was a horny summer" implying that the 3 heroines, mabel pacifica, and wendy, have already had an orgy with dipper, which just makes me less interested, why not make a game of that summer then from dippers perspective? That'd be more entertaining than this shit show.
3. Mabel is coming off as a real slut, I would have enjoyed the game a lot more if it retained mabel's personality about being ditsy and interested in relationships, but essentially being a virgin and clueless about how one goes about one; Hell I would have rather enjoyed the game in a more 4 elements trainer styled fasion where we train mabel, wendy and pacifica.
There was real promise in this game, but I have no clue on why they squandered it on cuckness.
