Cosmic Express ($5.99), a fun puzzle game by Draknet — the maker of the awesome A Good Snowman is Hard to Build ($5.99) — is on sale for the first time today. The game describes itself as “a puzzle game about planning the train route for the world’s most awkward space colony". That’s quite accurate, really, as your job is that of space-aged transit planner. You visit a series of galactic outposts and must figure out how best to setup a train line to pick up a bunch of cute little alien folk and drop them off at their destinations. The aliens are either lazy or it is super dangerous to, you know, walk anywhere and they need door-to-door service. This is made more difficult by the fact that buildings and lunar rocks are already all over the place. It’s a fun game with a ton of levels you can jump around to play, which is good, since it is also very challenging and easy to get stuck on a level for some time.

Both Cosmic Express and A Good Snowman is Hard to Build are a buck off for a limited time. If you enjoy challenging puzzle games made by a developer that really gets the genre, now’s a great time to pick up a couple of gems for your collection.
