I think it'd be nice that for the browser it could maybe ask you what controls you prefer and mobile can be an option, or you could perhaps make different download types as well? Either way I'd love to play this game because it looks great!
some time in the future i might implement mobile support. however i would likely need to change a few thing to get the tile set to load and to correctly handle the inputs for mobile users. it will likely be a while before i attempt to get it working for mobile.
