I just replayed the latest version. (with the fps indicator)
I managed to get to 32 before dying

Something weird is going on, sometimes after I'd died, and was surrounded by 6-7 orcs, the frame rate would drop to 3fps. Other times, I died and was surrounded by 10 and it was a consistent 20fps. All in all the framerate seems to be a consistent 60fps when walking/jumping/killing.
You might want to consider going for the 30day Unity Pro trial to access the profiler. It really helped me identify my performance problems. (and as long as you don't use any Pro features you can then just end your trial and go back to the free version without any problems)
