Have you considered creating a mobile version of this game? While I really enjoyed this game when younger, it was phased out for me by other desktop computer games. I could see this game doing really well on mobile devices where it wouldn't have as much competition. Mobile devices now have the processing power to support games like this, and the input system could be adapted to allow nearly the same level of control, but with touch controls.
If this is something you have considered or are interested in, I would like to offer my services as an experienced game designer free of charge to help make this idea a reality. Spiral knights was an extremely entertaining part of my youth, and I would like to see it live on to future generations of gamers.
Thanks!
FYI you should probably graveyard the duplicate post of this, just edit it and move it to the graveyard (don't leave a shadow copy).
Anyway, a mobile port would be cool and there's definitely a good control scheme that would fit, but the problem is that if I remember correctly SK runs on Java, and for mobile it'd probably have to be built from the ground up, and I'm not sure if GH is up for that right now.
