There's nothing in this world as determined as a hungry penguin, as this platform jumping game proves.

The object of Greedy Penguins is to guide your little penguin down a series of platforms as the screen scrolls upwards. This isn't as easy as it sounds, especially when you remember that penguins can't fly.

You can choose one of four different penguins (Daniel, Bonnie, Justin and Doud) who you must then guide down a series of levels, gobbling fish and collecting coins along the way. Not all the platforms are safe to stand on - some have spikes on them, some fall away when you stand on them and others send you shooting back up in the air. All this serves to make it a tricky and, at times frustrating quest, which will take you ages to master.

There aren't much in the way of options - there's only one difficulty level and you can't even enter your own name in the high scores chart (it just records the name of your penguin) so it's hard to keep track of scores if lots of you are playing the game. One neat thing though is the online multiplayer mode, where you can hook up with other penguin pushers over the Internet and challenge them.

The graphics aren't that tasty but if you're hungry for a challenge that Greedy Penguins will certainly satisfy your appetite.
