It was really fun!
I only quit after the game broke and didn't give me anymore money, even though my counter was at +4m per second. My temperature did raise to 81°, but that didn't seem to influence it.
I’m really glad to hear that you enjoyed the game!
Regarding the temperature, it actually does influence the game, but in stages! The game features a Heat System that directly scales your production multiplier based on temperature.
When you were at 81°, you were still within the ‘Safe’ zone (which spans from 20° up to 100°). In this zone, the multiplier is exactly 1.0x, meaning your earnings progress normally—which is why you didn’t notice a change!
Here is how the system breaks down:
Over 100°: The game enters a Warning state, and your earnings drop to 70% (0.7x).
Exceeding Max Temp: It triggers an Overload, punishing your income down to just 20% (0.2x).
Below 0° (Sub-zero): This is where the magic happens! Freezing your system boosts your profits. If you manage to drop it all the way to absolute zero (-273°), you get a massive 4.0x multiplier!
And that is exactly what the Fan is for! Using the fan to cool things down into sub-zero temperatures is the key to unlocking those massive revenue boosts.
