2- planning to release your game on pc ? It has clearly not been designed for mobiles anyway (the gameplay and controls are too complex). But just note that there is practically no html5 market on desktop, and that the pc/mac/linux world requires a higher quality standard than mobile.

I think you should consider rewording this statement. I get what you were implying with it, but I believe the creators of "Hotline Miami" and "Heavy Rain" Could tell you that there IS a html5 market on the PC. A rather quickly growing one at that. People have been turning to indie devs for awhile now and breakthrough games like Braid, Minecraft and the above mentioned have shown graphics are a sole requirement to sell a game.
It is however a much different process and environment than mobile, given that your only true strong outlet is to either get published or self publish on portals like steam. There is also still and probably always will be a market for the small simple browser based games. Lots of websites host their own kind of arcade and there is a way to profit in that sector as well.
Obviously currently mobile is your biggest market, but unless you are planning on pumping out several simple games and licensing them, you will face several similar issues you would on the PC. Namely one being over saturation, yes mobile is a great platform for simple html5 games however EVERYONE knows this and are exploding the market. Getting your game noticed is hard and requires some good marketing to get it not buried by the daily game spam.
