That IrisM or whatever it's called has nothing to do with us, or the game Iris Online - it's just some generic mobile game reskinned with the character/NPC and (some) monster models from Iris. The maps, quests, story, systems etc. do not resemble Iris Online at all.
I have considered making a mobile version of the game but so much of it would need to be changed for the mobile platform, it would become a completely different game in the end. Could be interesting though.
