This one is frustrating to say the least. You control a little green flea chappie who has to jump his way through some screens. Move the joystick left, right or up and a green bar representing your jump strength appears.

The longer the bar, the stronger the jump. You need to be pretty exacting to get the jump right. If you hit the scenery head-on, you bounce back.

There are a few nasties about that you need to avoid. Sounds reasonably easy although it isn't, actually. It takes a while to suss a possible path and even longer to make it, and to make matters worse it's against the clock.

At least you get a warm satisfying feeling when you get through a level.
