What is Color Drain

A puzzle game that
feels impossibly good.

Color Drain is a hybrid-casual satisfying simulation launching first on Android. You control a vacuum nozzle and drag it across 3D low-poly city dioramas — parks, buildings, streets — revealing the vibrant color hidden beneath as you race the clock. Simple to learn, impossible to put down. iOS coming approximately 2 months after launch.

100 hand-crafted levels across 10 chapters — all built. Levels 1–4 are an untimed tutorial; from there, drain faster to earn 1–3 stars based on time remaining. If the timer runs out, watch a short rewarded ad for +15 seconds — or accept the fail and retry.

100% Free to play with optional cosmetic unlocks and an ad-free option. Built with Unity by RDD-Labs — a two-person hybrid-casual studio in Israel obsessed with polish and feel.
