By placing arrows from the mouse generators to your rocket, you can guide the ChuChus to safety. If only things were that simple though. For starters, you can only place three arrows down at a time, placing a fourth will remove the first one you placed from the field. To add to your frustration, if a KapuKapu walks into your rocket, you'll lose a third of the mice already inside. For those of you with short attention spans, this simple rule will sum it all up.
Mice go in, cats go anywhere but in.
Added to this mix, are an assortment of power-ups. Represented by a little pink mouse with a question mark, getting one of these into your rocket will cause any one of a number of random events to occur. Strategy quickly becomes an integral part of winning, as you need to decide when to go on the offensive, and when to defend. Choosing the wrong option can cost you dearly. The gameplay is mind-numbingly fast, and I'm looking forward to finding out just how well this translates into portable form.
