Bloody Fun Day is a puzzle Flash game developed by Urban Squall and published by Kongregate on March 12, 2009.

Players control one of a family of three grim reapers and are tasked with moving around an island of hexagonal tiles, killing creatures called Cuties in order to replenish their own life force.

Only the red ones restore life; the others charge special abilities that give the player more ways to kill further Cuties.

The game's theme was inspired by the short story Everything Can Be Beaten by Jhonen Vasquez, which features a monster that clubs animals to death and is unable to interact with them in any other way.

Some issues, such as the lack of special effects and enemies, were highlighted; this did not prevent reviewers from rating the game positively overall.

[4] Initial development began in November 2008 when Urban Squall met in San Diego for their annual meeting, 2008's theme was 'a game in a week'.

The developers hired two adjoining hotel rooms and opened the connecting door, allowing them to concentrate solely on creating the game over a period of five days, resulting in a demo.

[5] The story centres on a monster called It, who spends his life in the confines of a single room, waiting in front of a chute that kittens slide down.

[6] Vue Weekly writer Darren Zenko stated that the game is addictive, finding himself playing for more than 8 hours in a day.

Despite this, Psychotronic praised the game's special abilities in terms of balance and interest, stating that the "three different families of powers support each other, making it feel like your efforts in one area can always be redirected to another.

"[2] He added that the increased number of turns needed to hatch eggs "can lead to some delightfully irritating close shaves.

[4] During play Zenko's reaper almost died due to a lack of red souls, but he managed to reverse the situation and fill the life bar; "even after all these years of gaming, that rush still does its neurochemical work".
