Before running game, run the configuration exe and check settings. Make sure you dont set game as fullscreen by default.
Heres my settings for example:

While game is running open "Input Controls" by opening Winlator menu (swipe from left side of screen).

There first enable "Simulate touch screen", then select "imouto" from the preset list.

After that return to game and press F4 button to toggle fullscreen. The rest just try playing and figure out by trying.

I attached relevant screenshots. To each step, but dont mind me using FFFox mod and color mod (those make game run even worse in some cases), but i like them so whatever. Worth it.
Extra step:
If you dont want to change input settings each time you play, make a shortcut of game (it will appear in shortcuts menu of Winlator and can even be added to your phone home screen i think).

(use right click to open this, by using 2 fingers to click or press rmb button if you have input overlay on)
After that, exit container and go to winlator shortcuts menu. And change imouto game settings. And enable those input settings by default. Them just click that shortcut to play directly. No need to open container separately etc.

Bonus for possible performance improvement:
I have been experimenting and noticed that changing to WineD3D and Performance preset might work better for Imouto Fantasy (if it doesnt crash). So try setting game like this.
