Old-school gamers may recall the joys of Lunar Lander, one of the earliest arcade games ever. The basic concept was to tip your spacecraft in the right direction and press “thrust” to try and bring it to a gentle landing on the moon. It was a gorgeous moment of early digital culture — a game composed of nothing but a war against physics. (There’s an emulation of it here if you want to give it a whirl.)

If you liked that, try out Blob Lander — an modern, hip update of that classic. This time, you have to pilot a blob in some sort of weird egg-craft around mazes, but the same basic rules apply: You’re fighting gravity and the ruthless precision of Newton’s rules of movement. It’s oddly compelling.
