I had that problem too, I solved it by modifying this:
/home/user/.config/unity3d/Tiger Studios/The Adventures Of Tree/prefs

Change the Fullscreen mode value to "0" and adjust the Windowed resolution.
<pref name="Screenmanager Is Fullscreen mode" type="int">0</pref>
<pref name="Screenmanager Resolution Height" type="int">720</pref>
<pref name="Screenmanager Resolution Width" type="int">1280</pref>

Save it and run the game.
