Happy to chime in - seems that my old Pocket Tactics account was no longer valid, maybe it didn't migrate over to the new servers/backend/forums?
I don't know what classes are there in Demon's Rise, but in case it doesn't exist, I was thinking of a "Chain Monk" (which you can picture as a cross between Mortal Kombat's Kung Lao and Scorpion).
He'd be a master of melee, with the ability to throw a long-distance chain to enemies to either trap/chain them for a turn or two (stun), pull them next to you for melee attacks, throw them across the arena and smash them against others, walls or the floor, and other nifty kind of things. You may even include a "boomerang blade hat" like Kung Lao himself if you feel he must have that kind of long distance attack.
Anyway, congrats on the great game - I see it getting a lot of positive comments both here and on Touch Arcade.
