Nice work! I love the pixel graphics and music. A few little technical notes: the trash bin is unfortunately directly underneath the "full screen" button when you're in the browser mode. Maybe a more central location for the trash can would have been better so you could easily play either full screen or windowed. Secondly I wish there was a restart button instead of Esc to quit and having to refresh the browser page. Maybe this code snippet could help:
get_tree().reload_current_scene()
