I there, thanks for trying it out, and I am happy the you find the mechanics cool!
We are right now in the process of updating the tutorial, making it clearer and with less irrelevant dialogue.
The disabling of mouse when the turn ends was something of a quick fix for controller support, but realized it had too much impact on the mouse and keyboard game play.
You will be able to scroll and pan during the enemies turn again in the next update.
