[The following text is part of my upcoming master’s thesis on the use of game mechanics in therapy games for children. This is just a rough first draft, and I gladly welcome all critique and suggestions – be it on a content level or regarding my use of language. As part of my master’s thesis I am analysing already existing games that are commonly known to be addictive. A lot of those games are Facebook games.]
Most Puzzle Bobble clones play quite similarly, with their graphics being their most distinguishing feature. The outliers are Bubble Island, which adds the element of time pressure into the mix, and Woobies, which comes from another era of online games, and lacks most of the additional game mechanics the Facebook games use. This core mechanic can be expanded upon, allowing the Facebook game studios to find ways to monetize the game. The game is easy to pick up and is equally well playable with any input device, be it a mouse or a track pad, making it an obvious candidate for a casual game. It is deceptively simple to play: aim, shoot, aim, shoot, with hardly anything that takes the player out of the flow.
