A random fact I bet you didn't know, Centipede was co-created by one of the very few female game programmers in the industry during the 1980s, Dona Bailey. This might not be of interest to you but as someone with an one time interest in games programming, I was intrigued.
There's a context to this of course: there's a new Centipede clone out on the app store! It looks pretty fun too. Hummingz EVO offers a few differences of course but fundamentally it looks like something that's bound to entice fans of the 1980s arcade classic.
It's only $.99, which seems worth a go as some of the boss fights look particularly impressive. Offering simple controls and two game modes, aimed at casual and experienced players, Hummingz EVO aims to be frantic fun. As you'd expect from an arcade game, there's global leaderboard support courtesy of OpenFeint. It looks to be the perfect game to switch your brain off and just have fun.
Take a look at the pretty neat gameplay video and see if it's your kind of thing.
