Criticality Experiment

Made for Jamsepticeye game jam 2025

Theme: Death is an Opportunity

After the nukes were dropped on Hiroshima and Nagasaki nuclear physicists turned their attention towards peaceful ends. Everything from medicine to carbon-free electricity and even space exploration has benefited from technology that made the bomb. 

You are working late at night doing criticality experiments on the demon core.

• Click to release neutrons 
• An atom can absorb 1 neutron and split, emitting 2 neutrons.
• Earn coins by splitting atoms 
• Longer chains are worth more
• Spend coins on upgrades
• Rank up by scoring high
• Tip: if a chain reaction is going on, stop clicking
• Download version has better audio compression
• Post your clear times in the comments!

For more info:

• The triangles are neutrons
• The circles are atoms
• You can click anywhere to release 2 neutrons
• Higher ranks make larger atoms appear that absorb more neutrons but are worth more points
• Clicking resets the chain counter (unless you have the momentum upgrade)
• The goal is to get a chain-reaction going with neutrons splitting more and more atoms
