I imagine it would be too much to port it to MV or MZ. My zoomer brain can't stand not being able to hold enter for whole sequences to speed up.
Yeah, it would require a lot of work to port it to MV/MZ (JavaScript) due to the code being written in Ruby, it's not worth the hassle.
About speeding up the dialogue, you will be able to do so with the mod, I've added skip text functionality to the message window by pressing SHIFT, it will automatically speed up all subsequent dialogues, also, you can toggle the message window visibility status (show/hide) by pressing S key in case you want the see the CGs clearly.
I'm currently working on a options menu overhaul, removing the v0.1 options menu, this one is kind of similar to the options menu you can find in MV/MZ games, you will be able to tweak any configuration (that I allow) inside this menu, currently being developed as you can see in the screenshot.
This new menu allows me to create options easily, insert them in categories and sort them manually, something that was impossible with the old options menu.
Also the menu is prepared to have any number of options, so I won't have to modify the script if I want to add a new one later in the development, unlike the old options menu, that was a NIGHTMARE to modify and insert a new option in it, believe me.
You will also be able to resize the game window, the only thing that comes to mind that the mod doesn't have unlike other MV/MZ games, is mouse support and better game art resolution, but they are way more complex that these other things and, in my opinion not that worth to do.
