The new project should have a couple of strong female characters, at least I think there are.
As for the tips, NTR isn't my thing so the chances are very slim I'd include something like that. Same goes for sandboxes, not a fan of them, so I won't implement mechanics like that. Bad endings serve a purpose of course, but I don't think it should be the only option in a game. So both Sisterly Lust and my new project will have the option to end on a high note or a low one and something in the middle at the very least.
