Cube Trains 1.0 is done, and available for download from http://cubetrains.com. It is a puzzle game about laying train tracks through a city, in 3D. It’s also free.
There is no limiting mechanism on the number of pieces you can place in a level, except for how many you can fit into a given area. While some games, like Isoball, will give you a set number of pieces to solve the level with, this merely limits the fun. Cube Trains lets you build as much as you want. Of course, there is some difficulty — it’s quite hard to actually beat a few of the levels, as there is barely enough room for you to build what you need to. In addition, each piece you use raises your score, and you may want to complete levels with the lowest score.
The game also features infinite undo and redo, along with the automatic placing of “obvious” pieces. This makes things much more convenient, in the long haul. If you’ve ever wanted to undo the last action in Sim City or Civilization, this feature is dedicated to you.
Cube Trains was made with the Frogatto engine. Because of this, it should be able to run most everywhere Frogatto runs. Currently, however, it is only really available for Mac OS X or Windows as you have to compile it yourself on Linux.
