How many GB is Quantum Contours?

2 GB

That is less than the typical Adventure game, which needs about 5 GB.

Leave at least 8 GB free: games need headroom to unpack updates.

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

From zero to hero: Outgun alien hordes in a rogue-lite bullet hell adventure. Fight through waves of randomized enemies in procedurally generated levels with fresh, new upgrades every run.
