Hello everyone!

You are responsible for the proper functioning of the Planck O'Clock system: if you take good care of it, you will earn bonuses and upgrades to install.

Play here : https://planck-o-clock.com/ (free, web browser, no install, no ads)

The game is functional; however, as it's a side project, I would like to get some feedback, particularly on its ease or difficulty, and on the balance of bonuses and the shop.

I just added a video showing a minimum stack to get started :

I will update this post as significant updates are released.

I estimate the progress at 50%, but it's hard to say, maybe only 10% according to players expectations...

Looking forward to your feedback.

Thank you.

Bruno

Update: For those who are stuck, a video has been added showing how to start the game.

About the game :

Planck O'Clock is a browser-based idle game where you operate a vintage clock instrument.

 Objective: Keep the clock running, detect particle patterns on the indicators, and earn Plancks and Bosons to unlock upgrades.

 Core loop: Indicators light up briefly — click the right ones before they fade to score points. Build detection streaks to climb the multiplier tiers and boost your income.

 Challenges:

• Power management — Your instrument draws real wattage. Install Lepton Farms, RotaLepton dynamos, and Photon Catchers to keep the grid alive. Overload it, and the breaker trips.
• Clock drift — The clock gradually falls behind real time, slowing your income. Run the PlanckTest (a 5-second full lamp test at peak power) to recalibrate — but if demand exceeds supply, the breaker cuts everything.
• Thermal trips — Lepton generators overheat under sustained load. Use the manual fan to cool them down, or watch them shut off one by one.
• Upgrades — TTL Extender doubles your reaction window. Planckoscope reveals hidden signal data. DecaMatic automates detection. VocaPlanck gives the instrument a voice. Expert Mode removes all hints for a x20 score bonus — but  penalizes mistakes.
• Decay & Legacy — Eventually your instrument decays. Prestige resets progress but unlocks Jokers, Prime Toggle, and other late-game bonuses.

=>  No accounts, no ads, no external dependencies. Just fun. Your save lives in your browser.
