Thanks for the feedback! I am glad you liked it. Teleporting should not happen, that is probably a performance issue in the web-version. I will add a setting, so that the graphics details can be reduced in the browser version.
The scout just moves quickly around to give vision to the map - currently not very useful I must confess. But that should change in the future.
When the construction facility is destroyed, it cannot be rebuild. In theory it is still possible to win, but very unlikely. Maybe you are right and I should let the match end when it is destroyed.
