I doubt whether Spiral Knights would be able to run decently on any mobile platform for a variety of reasons:

1) L A G. People already complain about lag, and it's most likely due to OOO's inability to provide for everyone an ideal amount of server processing dedication and network connection. If Spiral Knights had a mobile app, server load would increase and mobile connections would be subpar for playing the game in the first place.

2) Processing power - mobile platforms generally have less of it. Even when I play on a computer with low graphics settings, my framerate sucks crap. Unless OOO is further able to lower the amount of power required for Spiral Knights, a mobile app is not feasible.

3) Interface - I personally think it's nearly impossible to create a mobile interface for Spiral Knights that would even come close to that of a computer. Your fingers would get in the way of your vision because there's simply too much for them to do in such a small area. Even if you could create an interface that had all of Spiral Knights' current controls mapped out, there's no way you'd be able to use it effectively enough to play the game well.

I'm sure there other people have mentioned more reasons that I'm not thinking of right now. The reason I'm sure of that is because the idea of a Spiral Knights mobile app has been brought up several times.

Next time you'd like to suggest something, please use the search bar to see if it's been suggested before, and read what people have to say about it before suggesting it again.

Also, next time you have a suggestion, please provide some details for what you would actually like to see developed. Perhaps my entire post is completely irrelevant to your idea, but I'd have no idea because you didn't specifically say what you wanted.
