How many GB is O.W.L.: One Wave Length?

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.

OWL is top down, rogue like bullet-hell that you can play with up to 1 friend. Everything is in beat, including your and the enemies attacks. With each new Instrument, new attack patterns unfold for you which will take you to your final obstacle; The Meowestro, the source of dissonance.
