The game is simple to learn, but very addictive. Your objective is to destroy all the fortresses on the screen by shooting laser beams at them. You control your ship by pressing the cursor keys or moving the mouse, and shoot by pressing SHIFT or left mouse. That's all there is to the game – but that's more than enough to keep you entertained for hours. Crisp graphics, nonstop action, plenty of enemy fire coming from every which way, and smooth gameplay make Wkobo one of the best coffee break action games I have seen. There is even a neat little radar screen you can use to track where enemy ships are coming from. Highly recommended, especially if you enjoy simple-but-fun shooters. Two thumbs up!
