I've been a big fan of local multiplayer games for a while, and have been toying with the idea of creating games that use very simple input controls. After using just a single button (zero dimensions) per player and having some success with that on Android, the logical next step is using exactly one dimension: a slider!
I have quite a few prototypes of tiny mini-game mechanics, and instead of limiting myself to one such method, I prefer to build a compilation where players compete in rapid-fire mini tournaments, a bit like Wario Ware, but simultaneous multiplayer, with more than the usual 4 players competing.
The Slider controller and its dedicated game collection enhance gaming in these ways:
