This is the flash source code for Dino Run DX. Have fun with it. If you make something cool or add something to the game, contact pixeljamgames@gmail.com and tell us about it! We might just put it in the official version.
Please don't sell anything you make with this code, unless it's totally unrecognizable from Dino Run.
If you can go through the trouble of swapping all the art assets and make something new, sure, go ahead and sell it.
Tell us about it though and we might just help spread the word :)
Any questions about the code? Email Miles at pixeljamgames@gmail.com.
