I know nothing about mobile publishing myself, but I have to agree with Adam. You could simply state that it doesn't work well as a platform for your game (you mentioned using the whole keyboard, for example) and that you don't think you would do well in that eco-system. Nothing wrong with that.
It would also be good to run your post through some sort of spelling and grammar checker. While I have absolutely zero ability with second languages, so I applaud anyone who does, there are errors on pretty much every line that I see. I think fixing up some of those would definitely help make this easier to read.
