Driller is a classic Game. The aim is to drill your way down to the bottom level without running out of oxygen or being crushed by falling blocks. Use the arrow keys to move and press the Spacebar for drilling. (Hold an arrow key while pressing Spacebar for indicating the direction you want to drill.) Blocks of the same color bind together, get more points for clearing out large groups of blocks of same color. Brown blocks can be destroyed by drilling atheist four times and while doing so can steal some oxygen from you!
