How many GB is Kilroy Was Here?

1 GB

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

You are stuck in an unknown place, completely alone for eternity. Every decision you’ve made, will make, and could have made somehow rattling around your head. The only thing you can understand is a rock, with a gratified picture and some text that reads ‘Kilroy Was Here’!
