I really liked this game. The Halloween theme is original, the mechanics all worked really well, the sound effects and music is fitting, and it's simplistic but endless. Bonus points as well for the cool trailer.  Well done you guys.  To improve, I would add some more detail to the background  (maybe make it look like a graveyard)    and add a variety of upgrades/items.

Solid clicker game, I really like the art and audio affects especially with Halloween around the corner. Some good upgrades too! I would suggest some sort of final goal/upgrade or even an ending screen so that the player has something to work towards, but otherwise, well done!
