It's a very good game, a quite good idea with the different paths, the different tasks, and the different endings. Could you please tell us how to get Ending 2?
To get Ending 2, choose to help Lieb (the mushroom being). Then, when you go outside, exit the map through the bottom, below the rocks. You'll meet a new character. Talk to them, and at the end of the game, you can choose to go outside to have tea with them.
