This is an amazing game. I have played it many times and each time I cry. Especially after I read the comments.
A very good job to the creator of the game.
I threw my plane backwards twice without the browser crashing and I got an achievement! But I did have to restart my browser 4 times for clicking on the plane before I threw it twice.
