CO2unt Down is my submission for the GMTK 2026 game jam (theme: count down). In the game, players slide water and carbon dioxide tiles side by side to decrease pollution in an increasingly populated town.

A grid of tiles represents concentrations of molecules across the town. Blue is H2O and red is CO2.

There are 3 special tiles, and they are described in the main menu.

You can choose special tiles between levels.

I made all assets except the following:
