I just played a bit of Windosill, because I saw it on Steam for $2.99, you can buy it off the website for the same price...but you can also play a bit for free.
It says it's the "first half" and to play the "second half" you need to purchase the game....but the amount you play is so little...(albeit really neat and imaginative)...that if it's really 50% of the total game...I'm not paying 3 bucks for it.
But, if three bucks isn't that much to you.....it was definitely pretty cool.
