Trick or Threat

It's Halloween's night. The old Tobias is trembling with rage: last year those naughty kids stole all his sweets! But this year he has the solution: thanks to a magic book he summoned a demon who for a little of his precious sweets allows him to summon powerful creatures to protect his home from the kids. 

If the kids reach the cauldrons full of sweets they will leave with the craved prize, but if the kids reach the house and ring the doorbell it's game over!
