Don't Overflow is a portrait physics-survival game about reading a growing pile and choosing exactly when to open the Drain.
Hold anywhere on the playfield to open the Drain. Release to close it. Every second of Drain Charge matters: wait for a Primed blast, rescue a dangerous pile, and keep objects below the Overflow Line.
Build each run with workshop tools and upgrades, discover new balls and blueprints, complete Orders, and learn the strange machinery hiding inside the pile. The controls stay simple while the physics, hazards, and choices keep changing.
Features:
- One-touch hold-and-release gameplay
- Physics-driven piles, jams, collapses, and escapes
- Upgrade drafts and distinct Valve Kits
- Special workpieces, pressure events, and late-run hazards
- Workshop goals and a collection of discovered tools and balls
- Offline play with optional sign-in
- Optional one-time Chicken Wing Pack that removes forced ads; no subscription and no gameplay power
Read the pile. Time the Drain. Don't overflow.
Read the pile, time the Drain, and survive a one-touch physics workshop.
