Ember Keeper

Six valves. One small flame. Three minutes to dawn.

The last ember needs energy, but feeding it carelessly will burn it out. Watch the gold ring for the next incoming pulse, then open the matching valve. The violet ring previews the pulse after that. Every open valve adds heat, so learning when to close the circuit matters as much as knowing when to feed it.

Survive until dawn without draining the ember or overheating the core. Each attempt is a short exercise in attention, anticipation and restraint.

Controls

• Click a valve, or press 1–6, to toggle it.
• Space or the close-all control closes every valve to cool the core.
• P pauses or resumes.
• R restarts.
• Enter or the start control begins.

Keep it alive

The theme drives the whole game: energy and heat are competing needs. Opening more valves is not always better. Give the ember what it needs, then give it room to breathe.

Made with GDevelop
