I lol'd but seriously Dreiecksdorf is playable at least... though better if it wasn't so damn flat. I thought it was fun and made for an entertaining stream.
I'm not a huge fan of the tiebreak maps but they were pretty tense at least. Nobody knows them but it hardly takes a moment to glance and work them out, they're very simple. The only thing I don't like about them is the idea that people thing they are somehow an "authentic" way of solving a tie. Whereas in reality they're just as abstract as pretty much anything else. To stream it was fun and I prefer it to repeat rounds, which I think are stale.
