5th hero on the tablet. Auto-translated

We managed to send the first Chukchi cosmonaut into orbit – launching 5 heroes from "The Tribes of the East" on an ASUS VivoTab Note 8 M80TA tablet (64GB internal memory, a tablet with Windows 8). The game runs normally if you use a mouse. However, the idea was to use the stylus that comes with the tablet. At this stage, difficulties arose: the pen has very high sensitivity, and it's unclear how to zoom in and out. Does anyone know how to: 1) reduce the mouse sensitivity in the game? 2) adjust the zoom in/out settings during the game so that they can be adapted for the stylus?
