Interesting map idea, but I fail to see any point to playing it. Basically, all that happens is that a whole bunch of units continuously spawn in the middle and fight each other. As for the starting cinematic, you've got it WAY too high for the map you've got, as when it rotates you can see the dark inside of your cliffs.
BAH, the hero gains levels far too easy as well, and you haven't changed any statistics of any of the units. I give it 1.5/5. Trust me, this is me taking it easy on you.
