Pretty cute game! I like the 8-bit graphics & music.
It took me a while to figure out exactly how the 'possess' mechanic works, and that I could possess multiple objects.
I got 'stuck' on level 3 - I guess I possessed too many objects because I didn't have enough candy, but the kids stopped coming and the game kept going. I had to reload the browser window, but I was able to beat that level when I tried again.
