But more reactor types are on the way. This game is in early alpha, so try it out and suggest the direction for the final game. Thank you!
This game is from the YouTube series "Vision of Fission" from Higgsino.

Patch NotesOfficial
Small visuals changes and beta build for new reactor type.
Dear everyone thanks for waiting for the update. I want to give you some insights. In this release there are some small visual improvements. (Like neutrons fading when absorbed). There is also some works on the next reactor type which should be a light water reactor, with the water flowing around to a "steam generator". The plan is to let the user be able to control more about water flow, water pressure and such. Now a beta version is released of this reactor without any tutorial. Hopefully there aren't any bugs, but the plan is to: - Iron out all bugs - Optimize game loop - Add more reactor types. - Use ALL of the income for a pro developer to polish the game. Thank you and let me know what you think, sorry for keeping you waiting.Read full article on Community Announcements (PernkDernets)Patch NotesOfficial
Thank you everyone
Thank you everyone for trying out the small simulation! It's very exciting to hear all the positive experiences. If you have any idea for improvements, anything, let us know! We are working on making the Light Water Reactor, where water is free to move around the reactor and warm up a heat exchanger, and also thinking about how to make the game loop more engaging with better UI Thank you!.Read full article on Community Announcements (PernkDernets)
