Paint and dry up to 10 walls. Earn Moments of calm and spend them on sequential upgrades. Pick a colour and cover the wall before the round timer runs out for a bonus - once it's fully painted, watching begins automatically. The paint dries at its own pace regardless of whether you watch. You will be rewarded with "Moments of calm": each watching eye pair earns for you; glasses and golden upgrades increase the return. Look away and the paint doesn't mind, but you'll lose 5 points on the spot for it.
How to watch: Keep your mouse pointer or finger pressed on the wall - lifting it counts as looking away. Only eyes on the paint earn calm.
