I like the jump sound and wacky collisions.  I figured that was intentional.  It's cool to see an enemy fall off the map straight at the camera :)

I like the idea though controls are pretty tricky. I definitely like bumping things off the map and sending them to oblivion though haha. I really gotta hear how you came up with a Jack O Turnip game though...

Note: lighting effects do not display in (at least) Safari. Display correctly in Chrome, though check your plugins (and possibly run incognito with them disabled) if game doesn't function as expected.
