A GMTK 2026 jam game built on the theme Count Down. Two clocks pull against each other: every reactor system counts down toward zero and must never reach it, while the evac clock counts down toward zero and has to. You have one cursor and too many gauges. Survive seven nights and you walk out.

About

One screen, one hand. Each system holds a value from 0 to 100 and drains on its own, and holding the cursor on one charges it back up while every system you are not touching keeps falling. The whole game is triage: which fire do I put out, which do I let ride, can I reach that one in time.Hitting zero does not kill you outright. A system at zero lights a 1.5 second meltdown fuse with a countdown alarm, and pulling it back above zero before the fuse burns out saves the run. That rule is why the deaths feel fair. The meltdown report afterwards names the system that failed, the cause, and every tool you still had in your pocket.Nights get wider rather than just faster. Night one is three systems draining at 4 per second, night seven is nine systems at 7.6 with a scripted boss leaning on the panel. Between nights you take one of three salvage upgrades, and the operator tells you a little more about what is under the floor at Site Zero.

What's In It

Seven nights, each a 32 second countdown, from three systems up to nine
A 1.5 second meltdown fuse at zero, so every death is telegraphed and earned
Three operators: Engineer for the standard run, Veteran to start with a stabilizer bot, Gambler for more salvage at higher drain
15 draft cards across manual charge chains, fuse recovery, automation, tools, and overclock income
An overclock toggle that doubles drain and pays salvage only while a system holds the 55 to 85 band
Five tools on the hotbar: Freeze, Slow-mo, Overcharge, Weld, and stabilizer bots
A scripted Zero Hour boss on the final night with six timed attacks
A between-nights story told in full screen scenes, written for one operator who did not take the evac
