Alva Majo, the developer of the game, has never tried Hawaiian pizza (pizza with pineaple) because he is allergic to pineapple and because, according to his words, "it stinks", so he made this game so people like him could enjoy (or suffer) the experience of adding pineapple to a pizza.

The game follows the philosophy of ShortGames, not "Short games", but ShortGames. The main difference is that a short game is just that, a game that is short, meanwhile, a ShortGame is a game that not only is short, but conveys the experience of a long game in a short amount of time. For example, taking the first level of any Mario game wouldn't be a ShortGame but a short game, since you are just taking a fraction of a game and it doesn't feel better by being just that. A ShortGame is close to what shortfilms are for movies, they are an experience on their own. Examples of ShortGames could be Morai, Thirty Flights of Loving, or Langeskov, The Tiger, and The Terribly Cursed Emerald: A Whirlwind Heist.

It's hard to talk about ShortGames since almost everything could be considered as a spoiler since they tend to last less than thirty minutes, but let's sum up the premise of Pineapple on Pizza based on what you see in the first minute: You are on an island. You hear joyful music. Everyone is dancing happily. Everyone except you, because you are walking around. Everyone seems to be celebrating something in harmony. Everyone except you, who seems to have some kind of curious conscious... From there, you will explore the island and discover as many misteries as your curiosity and exploration allow you to.

The game is not only radically original (at the end of the day, it is trying to adapt a flavour into a videogame) but also surprising and delightful.

And it is free, I mean, what else are you looking for? Go play it!
