This is and old game I made a while ago, it's sort of like a puzzle platformer. Use the arrow keys to move around. Mouse to shoot your laser and break the rocks, destroy all the rocks in a level to pass to the next. Press A to shoot out your analysing laser and analyse plants for extra points. Press R to restart the level if you get stuck. Also press this if the game lags. Press space to elevate the rover and get over tall obstacles. If the BODY of the rover touches lava, you restart the level. Press 1 to skip a level.
