Playability: 2.5. Let me state my biases up front. I don't like race for life, I don't like mazes, and I don't like countdown timers. So naturally this is a race for life through a maze with a timer counting down. Even so I thought it was fairly playable and would have rated it as a 2 but I added half a point to compensate for my bias. The first time through I got wiped out but that was just a recon expedition, I got the entire map scouted before my second horse archer finally succumbed. The second time through I won in 3 minutes. You could do even better.
Balance: 2.5. You are totally outnumbered but with a little deft maneuvering you can avoid most conflicts. Also, the designer has salted the map with Gaia BLP's which you can use as emergency medic stations. Although I didn't need them.
Creativity: 3. Definitely not your random build and destroy scen.
Map: 3. I can barely see a random map beneath the enemy buildings, but the map has been very heavily reworked into a maze like city.
Story: 3. Lots of work in each category here.
