Latest has options for window size, "input repeat," and others in the main build. Also toying around with some fonts to make the menus more readable. Leave some suggestions below!
The "input repeat" option can be found under Options -> Controls/Gameplay Settings. That option controls how quickly the game repeats inputs that you hold down.
When you're idle, the game will run at "Game Turn Speed" (aka Speed, aka the meter in the upper right during the game). When you're holding an input (such as the direction keys or the 'wait' button), it essentially runs at "Input Repeat Speed".
A few of us in testing have found that "Medium" is a good setting for that. If your Game Turn Speed is set to Slow or Turn-By-Turn, it'll give you some thinking time; but it lets you execute your moves at a speed greater than thinking time.
(One other way I've seen the game typically played is to set the game speed to Turn-By-Turn and hover your finger over the Fast Forward button, then hold that button when needed.)
I've also bound 'Fast Forward' to the button 'X' in addition to 'RT' by default so that it's easier to access. This won't override your current settings, so you'll need to either bind that button manually or reset controls to the default configuration to get it to work.
Happy Squaring!
