New version of ElectroTrains now available on the App Store. The new version has (much requested) support for Game Center so you can now see how your scores compare to players around the world.
The leaderboards are starting to fill up, and someones already beaten my best score on map 2! :-(
I've also recently got hold of a first-gen iPod touch, and discovered a few graphical glitches - so these have been fixed up too!
