Spoiler Alert is a platformer that you play backwards. I'm not joking. Developer Megafuzz describes it as the first game you'll uncomplete.
We first caught wind of Spoiler Alert during Casual Connect last month, but now publisher tinyBuild has taken to the megaphone to announce its imminent arrival.
As Spoiler Alert is played backwards, timing jumps and dodging fireballs is going to take some getting used to. If you don't get the timing right then you'll have to wind time forward and try again.
It also has a element of puzzle-solving, as you need to quickly figure out how to undo all the different things you previously did.
There's also a touch of mystery to the game. While the large boss usually found at the end of a game has been defeated, the world saved, you'll be travelling back through time to find out why that needed doing in the first place.
Aside from the 100 levels designed by the developer, Spoiler Alert has an Endless Mode and a level editor. Seems like you could be travelling backwards for a long time, if you wish.
Spoiler Alert will be coming to PC, Mac, and Linux shortly, with the iOS and Android versions following soon after.
