Celsius

GMTK 2026 Submission

Celsius is a city builder where you watch the temperature and count down the degrees... or count down the dwindling population.

Inspired by recent heatwaves in my country as I watch the portable air conditioner fight against the outside temperature.

The goal is simple, grow your population whilst bringing the temperature down to normal levels. Place homes to house your meeples, develop park land to attract them, and build power plants to run it all. More meeples more money.

How to play:

• Click an option from the build menu to select a building.
• Click a tile on the world map to place the building.
• Click a placed building to inspect or sell.
• You can cancel building by right clicking.

Should take roughly 10 minutes to complete. I didn't have time to play test it extensively so would love to hear your feedback regarding difficulty. Let me know how fast you completed the game!

Conversion table for Fahrenheit:

20°C = 68°F
30°C = 86°F
40°C = 104°F
50°C = 122°F
