Hello! Mystic Melee is in the Indie Megabooth area at PAX West! Find it in the Serenity Forge booth, 755 :)
On the development side of things, there's a new feature that really ups the ante in FFA deathmatch: Powerups! These special powers spawn at Arcane Altars. The player who nabs them gains a great advantage, like flying, triple damage, megaheal, and more to come!
Here's an example. With Megaheal, don't even care about taking damage!
In addition, I've been working on a system to help people get into online matches in a more automated way. That and the timing of some events have pushed back the release, but we're on track right now for the release later this month!
