Hot Pixel is a collection of super-short mini-games that borrows almost all of its design from Wario Ware Inc. In case you were in any doubt as to how far Hot Pixel borrows from Nintendo's Wario Ware, the game spells it out at the very start: "get what to do... find how to do it... finally perform!" That's how, according to the opening video, you play Hot Pixel, and, you may recall, it's how you play Wario Ware too. You wait for your next mini game; you try to work out what to you're supposed to do, and how to do it, and in the next five or six seconds you do it.
But really, how could you possibly be in any doubt about how far Hot Pixel apes Wario Ware? In terms of the overall structure of the game, it's almost precisely the same: there are ten episodes to unlock, and each one consists of ten mini-games that last about five or six seconds each, and halfway through each episode the games start speeding up and getting more difficult, and at the end of each episode you'll find a slightly longer boss encounter. And once you've unlocked each mini game, you can practice it and play it through to achieve high scores to your heart's content. And if you like you can play some of them against your friends in multiplayer mode.
And it's not just the structure that's almost precisely the same. As you play through each of the five- or six-second mini games you'll notice that many of them are almost verbatim replicas of the games that, if you've got any sense, you'll have already played in Wario Ware. Like the one where you have to jump your skateboard over things. Or the one where you have to shake a tree. Or the one where you have to chop something by hitting the button just when the power gauge is at the end. Or the one where you scrub a hand. Or... the list could go on - and probably will do at the offices of Nintendo's lawyers, because Hot Pixel is absolutely shameless in ripping off Nintendo's masterpiece.
