Super cool! Took me a while to realize you actually did use the art pack.
I love the polish, except for the menus I wouldn't have guessed it was a jam game.
My only real suggestions would be to improve the menus and please add a 'zoom out' button or a way to look around.
The farmer looks like Rex from Xenoblade2. 10/10 would kill again (Oh! It could also be fun if you have to fling the farmer offstage or into spikes instead of just grabbing him)
