Hey, I like the game but it's hard not to comment on the matchmaking service.
A couple of suggestions:
-Show number of players in game and/or players searching for a game, any UX book would tell you feedback reduce frustration, which should be a top concern in a waiting que..
-Show estimated time, nice bonus feature that promotes the same thing, has it's issues.
-The screen/sound itself gives me a headache when it should be soothing me while I wait. A 3 sec endlessly repeating loop with a flash wasn't a good idea.
