They say its for a limited time only. The new update was just released. I downloaded it last night when I was bored. I saw "MEGA SALE" and naturally, when "mega" is capitalized, you're obligated to take a gander, so I did, and I was wanting to get this game at $5 but couldn't justify it, but at $1, I couldn't pass it up. Its a great puzzle platformer with some cute graphics and nice progression in difficulty. As a bonus, the music drives my girlfriend up the wall Its the first game I've ever played that had her asking me to put my headphones in. I like the music. So yeah, there you go, just a little heads up for a great game on sale, worth your attention.
