"Der Dodge" is a game built with idea of simplicity in mind, so that everyone can pick it up in his lunchbreak or while being bored and try to break the highscores without too much hassle.
The ingame instructions explain everything you need to know to play the game. There's a little bit more to it, though, which is explained below.
You control the Square with the mouse and have to dodge the red objects. You gain points by collecting the incoming circles. The more circles you collect in a row (up to 6) the more points you gain. The circles you collected "stay" in you until you either collected 6, touch an enemy, or let a circle pass the top of the screen. If you touch an enemy with a circle, you loose the circles, if you touch and enemy without any circles, the game is over.
I probably could have done a lot more with the concept, but being my first actual finished Flash game, the code kinda mutated into something I can no longer properly control. I learned a lot from it for future projects, though.
