King's Cross station in London is now home to a very interesting playable Christmas tree designed by Robin Baumgarten, creator of the one-dimensional dungeon crawler Line Wobbler.
Funded through Games London and Network Rail, the installation and its incorporation of a physical space is a unique way of showcasing alternative games which feature different input controls and a minimalist design.
Standing at six meters high (nearly 20 feet), it contains 200 LED lights and has the trappings of a traditional dungeon crawler. Players navigate obstacles and fight enemies by bending the controller forward and back, while enemies are attacked by flinging the spring.
The installation is an adaption of Line Wobbler with some additional Christmas adaptations. "The game itself is running on a handful of Arduinos." Baumgarten explains, and uses "around 100m of addressable LED strips."
The LED tree will remain in King's Cross station until January 4th, 2018.
