How many GB is O7?

1 GB

That is less than the typical Indie game, which needs about 3 GB.

Leave at least 7 GB free: games need headroom to unpack updates.

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

o7 is an infinite vertical scroller where the floor is Lava, you have to go up as fast as possible and try to stay alive.
