✦ AI summary

Players praise the game as genuinely fun and engaging, with particular appeal to those who enjoy management mechanics and detailed systems like nuclear reactor control. Common feedback suggests the core gameplay loop is addictive and works well, though the tutorial could better help players acclimate to the specific control panel layout and procedural steps required.

Decided I was mature enough to run a nuclear plant. Played with chemicals enabled. Became fustrated with Mr Electron dinkhead denying me a chance to shut down my plant for maintainence, even though my transformer was 60% worn, reactor xenon poisoned. Got fed up, pulled rods completely out, maxed boron removal pump. Put on my hazmat suit, went to train. Waited for the glorious bright light. 10/10 would do again.

IT seems like could be a fun game but the tutorial takes you through startup and then the plant quickly starts giving alarms and doesnt seem to react to the changes to fix the problems, The tutorial seems to be flawed on startup procedure to have a stable startup
Not recommended Sep 12, 2026
Pretty negative impression for me. Every time you need to adjust the graphics settings, the game needs to restart. For this game in particular, that means restart steam and log back in, every time. The stop service doesn't work and task manager cant identify it. Strange, right? If you die in the game and go to menu, and start a new game, the WASD and look around controls no longer seem to work. I am a sucker for these power management games, they're highly intriguing. Being able to harness electricity and get paid for it. Being able to see the problem through lights and gauges, all pretty awesome stuff. Unfortunately, I can't recommend it if accessing the game is gonna be a pain in the cheeks, every time. I'd improve it later on if the next patches get this game in a better working order. I can understand where the dev is coming from though, has a family and other responsibilities. Nevertheless, this may not be fixed for some time. Seriously though, really good concept.
