I completed the game! YAY! and the mystery upgrade is the animals from Learn how to fly, headge hoghe and others
i finished this on armor games and not newgrounds no medals for me D: but its still a great game
Good concept, but...
This game needs a better take launch mechanic. The airplane barely goes anywhere with the surrent one even with several upgrades.
simple and effective
who knew that games about paper planes could be fun? :P
I really love this game
The game is like a master piece. it runs really well without any interruptions and the RPG like leveling up system is just bomb. Way to go! Give ya self a pat on the back!
