A downloadable game for Windows, macOS, and Linux

You were as excited as everyone else when they started building the power plant. Your town would become the site of a scientific breakthrough and burgeoning infrastructure. Now the city is in ruins. The streets are blocked, covered in the rubble of collapsing buildings and attempts at containing the fallout after the incident.

Those who survived were evacuated, but the disaster is far from over. The situation is still on the verge of poisoning the continent for good. They say what remains of the core could explode any day now. Someone has to go in to stabilize the reactor.

Find the power plant schematics, traverse the underground passages, reach the reactor and use the stabilizing reagent. Will you make it before all is lost?

Well, if it makes you feel any better, this is the second time I played a horror game and died several times. Nevertheless, I loved the game itself. For a game with such a small footprint, a lot was going on, and it took me some time to figure out what to do and how to do it. Thanks for 10 minutes of sheer fun. Well done and kudos to ll involved!

I had a good time! Despite being truly, genuinely terrible at jumping puzzles, it was fun. I liked the atmosphere, I liked the story, I liked the nuclear goo.

Check it out if you want to kill a little time ;)


Thanks for the entertaining playthrough! Btw how did you find the game?


I enjoyed it! I didn't encounter any glitces or bugs, I though the art style worked for the setting, I liked the story, and it didn't overstay it's welcome or drag on too long.

Nice little game, enjoyed it very much!


I came in expecting some spooks but instead I feel like I saved the world. Or maybe I failed and I didn't notice. I'll pretend I saved the world. 

Hello, I played this game and I really liked it, the concept here is very interesting and the platforming was neat as well, good work :)

Good Story but I wish it was a bit longer. Keep up the good work!

Thanks for playing! The game was made in just 72h for a competition so as you can imagine we would have done a lot more if we had the time. We might do just that after the voting has ended!
