Green's dog is adorable!
Great game, really liked it. I even got teary eyes at the end.
The art is great! I wished the background was a notebook or something.
I kind of imagined it as red's notebook and her drawing her friends to keep her calm and fight her depression.
I will also note that in terms of game deisgn, I didn't really think much about what to do, or who to call.
Would be nice if there were different enemy types, and each color is effective on each enemy type, but that is a bit more complex and in a game jam must be hard to do.
Well done!
