Sure thing!
There are 12 themes. Each theme consists of three randomly picked emojis and may be interpreted in any way you like.
People are encouraged to pick one theme per game, but they remain entirely optional.
All themes are listed on the game jam page here: https://itch.io/jam/make12-2025#Themes
You'll see in the "Themes" section a list of 12 items, each one corresponding to a theme. Although they are numbered, you may choose them in any order. Next of each trio of emojis, the names of the emojis are written in plain text to help comprehension. I added because of some particularly unclear emojis, such as the "Notepad with decorative cover".
