Thank you for giving it a try! :-)
I store all games that have been played in a database. From the timestamp of your comment I could determine the two games you played. I watched the replays of those games since I am always interested in how others play my game. What I have seen is that you do not use the possibility of moving diagonal. This would have given you a lot of potential to overtake. In order to move diagonal, you have to play with the numpad or alternatively use the keys [Q,E,Z/Y,C] next to the [W,A,S,D] keys. What I learned is, that my game needs a tutorial to teach the basic concepts since most players will not read the manual nowadays.
I will do a second run on your game Schachkampf soon.
