We played this with a handful of people last night. Overall it was a lot of fun, but I think there are some minor issues that should be worked out. The biggest issue for us was that it's extremely easy to camp blue's final spawn, since it's a tiny room with a single exit. Either expand the room and make the door full width or make the room bigger and add a second exit. Alternatively you could block red completely from the room right outside as well... the one with the ramps in it. Putting doors on that room and making the current spawn door glass would solve the problem.
