How many GB is Ballrun 3D Marble Maze Speedrun?

0.2 GB

That is less than the typical Simulator game, which needs about 4 GB.

Leave at least 6 GB free: games need headroom to unpack updates.

The figure is the storage Steam lists as required for this game, not a measured download.

You choose to play BallRun not because it is easy, but because it is hard, because the goal will serve to organize and measure the best BallRunners and their skills, because that challenge is one that you are willing to accept, one you are unwilling to postpone, and one which you intend to win.
