It is a very difficult genre to call attention into.
I believe the best you can do is to have it on many stores you can and produce more games.
People that get your other games will eventually look into your production and it may be easier to market it this way.
I think (IMHO that applies only to me) that the best way to go is to have somewhere around 5-10 nice games going before money pops out.
Keep it up, Desura is also a great place! Reaches more people, but it is more crowded
