Playing two-handed (arrow keys to move + mouse to click) isn't as nice as just using the mouse to move around, so that mouse-snapping bug needs to be fixed. Someone else already mentioned it though.
I didn't even notice the pumpkin animation. Maybe add some zazz when you click on something successfully, like stars coming out from under it? It'd draw your attention in and it's good to have effects that emphasise when the player did something good!
Cute game.
