Hi! Thank you for playing. Letters management is kind of tedious, I agree.
As for the abilities and colors, it goes like this: each furball has a unique ability. It’s either martial arts, magic, diplomacy, or healing. And each ability has its color. Each task also features an important ability for solving it, and the pin for the task is colored in a respective color.
There must be a better way to organize this information with icons, etc., but we didn’t have time to fully develop this aspect.
