BoulderGame This is our version of the classic boulderdash game. Some of the levels are quite hard. But you get an access code every time you reach a new level. Controls You can move your player by using the arrow keys. If you get stuck somewhere, pressing space gets you the next live. The door to the next level will open when you have collected enough diamonds. You can see how many diamonds you have to collect in the status bar. Download If you want to play this game without being connected to the internet, you can download an Executable Jar File. You will need a current Java JRE to execute it. JREs are provided here.
