If you found Crow in Hell and When Pigs Fly rather tough (congratulations, by the way - you're officially a member of the human race), but like the idea of piloting a fragile airborne something around large, hazard-strewn environments, go for a spin in Cluster Lander.

Players take command of a little egg-shaped craft with four boosters, one per arrow key. Each level contains a data file with coordinates for the next, and your job is simply to retrieve it and return to the teleporter.

Did I say "simply"? Because it's anything but simple. Well, it is actually. Sure, there are floating mines and electrical forcefields and gun turrets and locked doors and stuff, but on Normal difficulty at least the ship is fairly sturdy. Floating arrows point up the next objective, so you'll have to try to get lost.

It's more of a twitchy, timing-dependent puzzler than an action game, but there is the odd shoot-out. Your ride has built-in stabilisers, but you'll need to knock it on its side to squeeze through smaller gaps.

Once you've beaten a level, you can race the "ghost" of your previous playthrough for bragging rights.

If exploration's your bag, try Small Worlds.
