There is a free game (no obligation to pay) with a good Halloween theme. The website has a link to its funny Halloween music, it is available here: In-Poculis Halloween game.
that game looks like a touch game we play at the pub here called Monster Break
Last night 'twas witching Hallowe'en
Dearest; an apple russet- brown
I pared, and thrice above my crown
Whirled the long skin; they watched in keen;
I flung it far; they laughed and cried me shame
Dearest, there lay the letter of your name!
