Use arrow keys or WASD to move. Click the tree to enter. Click on Squirrels to talk to them. Z to sleep. (or click on nest inside of tree) E to dance. R to stop dancing. (kinda buggy) Click the black arrow to go in and out of the tree tops. I key is to... sit. L key is to eat. Have fun! :)
I just fixed a music bug and some more things, like having to eat to not starve. Also look at the remixing tree, it will be easy to find another project made by me, and in that project you don't have to eat, it is the project named 'The Squirrel Game remix (without hunger)'.
