Talis got the test server up last night (forgot to tell Schro about it since it happened while he was at work) so we can finally start testing some of the game mechanic fixes instead of having to wait for Talis (which is why it takes so long to fix game mechanic bugs... Which has only been said several dozens of times), as well as start testing some new content. (New world, endless tower, db/bb rooms, etc...)
