Hello,
I am Hermann, a scientist and software developer. In the past I have created a number of mobile and hybrid mobile/web based games.
Having a designer on your side is a huge benefit - I enjoy bringing cusomers' game ideas and visuals to life. Speaking of game ideas - your post does not mention what kind of game you require in any way. I have experience with physics simulations, minigolf, puzzlers, and some proof of concept shooting and running games as well es recreating old-school arcade classics.
What is the idea of in-game currency transferred to a website? Are we talking about real money or only in-game currency?
My offer is to create a HTML5 web game which runs on all devices and browsers without any additional plugins.
If you're interested, please feel free to contact me at any time to discuss goals and possibilites.
Kind regards
Hermann
