You made it through university, got your PhD, and now you have been selected to work in an top secret experimental facility which promises a way to generate infinite energy through the combination of various strange particles.

Use power to generate curious molecules, check their properties in your logbook, monitor their progress through your trusty E-merge device, and try not to let the reactor overheat!

And don't worry about those armed guards on the way in, as long as you meet your quota then you'll have no problems...


Web version works, though some assets may take some time to load or not at all so we advise playing the download version.

Also the audio in the game is quiet by default but can be adjusted in the settings.

If stuck then check the logbook in the lab for tips!

Combining molecules increases power, whereas molecules colliding with the edges increases temperature. Experiment to find the best combinations!

Check the in-game credits at the end of the day for how to activate the endless "God Mode" if you just want to mess around!

would be reale nice if you explaiend how to play 

There is a manual on the table which explains most of the mechanics. Other than that's it's just clicking and experimenting with different reactions.

Just to add to IQuick's comment, combining molecules generates different amounts of power, and temperature increases based on the speed and amount of molecules colliding with the edges! I hope this helps, and thanks for playing our game!
