Alright, sorry for being rude, jesper.
Look at some sites where they are advertising for games.
http://www.ea.com/official/battlefield/battlefield2/us/
like that.
First, add more pages, have a "screen shot page", a "download page" and others.
Next, put all the info about Jesper games on the top of the home page where people can see it. Also, only put one or two screenshots on the homepage if any.
After that, get a logo to put on the top of your site, but that's easy because I made one for you.
There you go, some constructive crit. I did a logo for you in five minutes, its attached.
