I'm actually surprised I'm the only pumpkin carving game to be honest, I thought it would be a recurring theme :P
I've had similar comments for the saw, and I understand how the pumpkin in defying gravity by having chunks floating in mid-air, but this is mainly due to time and implementation constraint. If I was to restart the project from scratch, I would probably be able to implement it properly, but it would unfortunatly take a lot of work to make it work with the current setup.
Still I'm glad you enjoyed your experience :D
