Yeah I beat it using MTOOL. Its one of the few games that I viewed all the routes and endings, every scene!
My favorite was totally unexpected. You beat the game and get one final choice, its super damn hot.
And the NTR is written in such a way that, depending on your choice, it does not diminish the cuck at all.
Like, an NTR ending that also made me really happy for all the characters.
Definitely following this dev to see what they do next!
