Cosmic Express is a charming sci-fi puzzler about planning out the railway paths of crowded space colonies, coming soon to iOS and Android.

It's the next game from the developers of the Gold Award-winning A Good Snowman Is Hard To Build, and Cosmic Express maintains its predecessor's colorful charm and tight levels as you draw the train's tracks to ferry cute aliens around.

Each alien must reach its same-colored home in the correct order, and trains will have limited space to carry passengers, so you'll need to methodically plan out your train's route on each stage.

Cosmic Express currently has no release timeframe besides "Coming soon", but will cost £3.99 / $4.99 when it releases on mobile. You can find more details on the game's site.
