So, I'm coming fresh from the playtest, and I'm definitely not disappointed. In fact, this is probably the best thing since Gold Rush. It's so much fun!
I saw two errors when playing, by the way:
You've got an error with the lights in RED's third base, right next to the exits. The ceiling seems to be completely black in that part, so I guess you forgot to turn off the shadows on the models or something.
You also have some error where, on the final point, the alarm sound kinda locks up when it's capped. I had this on my map too before, and I fixed it by basically disabling the cart and everything that was related to it when the point was capped, so you should probably try that.
