click the green flag many times to make sure the project starts properly. Use A and D or arrow keys to control the plane if you press "e" at the right time, a secret ending may get unlocked. otherwise, who knows what'll happen. [semi-spoiler] after toast says "or even who caused it" there might be a slight pause before the scene continues. i couldn't figure out how to eliminate the pause, but i'm just putting this here to let you know that isn't the end of the project.
if you change the "o" in "toast" to a "y" and move it to the end of the word, toast will become tasty, which also occurs if you put honey on it.
