If you've got a long bus or train journey ahead of you and want something to relieve the boredom then you could do a lot worse than installing MadBeetle on your Pocket PC or Windows Mobile Smartphone.
This fun game sees you take the role of Madbeetle, an ugly, angry little creature who's stupidly managed to get himself stuck inside an underground cave (no wonder he's so upset). In order to navigate your way out of this labyrinth you'll need to avoid monsters, solve puzzles and jump over various obstacles.
MadBeetle proves to be quite a fun adventure with a smooth learning curve. It starts off at a gentle pace giving you time to learn how to set off bombs, open doors and avoid obstacles. The game is controlled using the number keys on your phone, or if you have a Pocket PC you can take advantage of the touchscreen controls. There's a lot to remember but you'll soon get used to it.
In terms of its presentation, MadBeetle is quite impressive, with small but well-drawn cartoon characters and an amusing soundtrack. The only slight qualm I had was that I felt the animation was a little slow.
Nevertheless, if you're looking for an engrossing adventure game to get you through a long trip, MadBeetle is good fun.
