With the combat there is an attack combo you do, but you have to get the timing right or else it just does the first attack over and over, which is what was happening with you. There is a 8 hit combo, and right click does a heavy attack that is different based on what hit you were on.
In my testing in the editor version going in/out of buildings always worked, I never got stuck in a building like that. I didn't do any testing of the compiled version.
Thanks for playing.
