Save The Pup

Save The Pup! is a flash game I created for my University course (Cert 4 in Digital Media Technologies), for an assignment. I have since completed it and now I wish to share my creation with the world so please give it a shot, share it with your friends and let me know what you think.
How to play:
Use arrow keys to move the pup, collect bones and avoid dirt.
There is a known glitch I didn't get wrinkled out before I had to hand it in where sometimes it glitches between levels, just reload the page to start again.
