-I really hate that on a game in 2018 I have to use the bct.sizer script in order to make this game larger and in windowed mode. Full screen mode is busted as fuck and messes with the screen resolution. Fuck that. Also, no mouse support? Fuck that, too. I want to have one hand on the mouse, the other hand elsewhere. That's how these games should work. If you're making porn games that require two hands, you're doing something wrong. Not kidding.
Just wanted to chime in with something I recently figured out regarding RPGM games. I used to get annoyed with the two-handed control schemes too, shit is annoying as fuck in a porn game-- I 100% agree.
But if you have a full-sized keyboard you can use the arrow keys for movement. By default the Enter key advances dialog, and the 0 key on numpad functions identical to the ESC key. Enter and Numpad 0 are both easily reachable with one hand from the arrow keys and figuring out that 0 = ESC makes RPGM games way more enjoyable for me when I'm (ahem) playing one-handed. I actually prefer that control layout over mouse-control myself, because mouse control is way slower for me when navigating menus and dialogue than just quickly tapping my way around with key presses. Just my opinion though.
And fyi, for a lot of RPGM games you can usually skip text by holding down CTRL. No need to spam Enter. (this doesn't work for all games but it works for most, including this one)
I know you've said you won't be playing this game anymore, but it's something to keep in mind for other RPGM titles if you ever play another one in the future.
