So.. i spent my day making this ^^
it's a really smooth pan-sliding menu that feels natural. I always wanted to make something like this when i first saw an iOS game using a similar method, and i really like the feel of my version.
It's not only scrolling vertically, but is also smooth-locking to multiple columns horizontally.
It has 7 rows and 3 columns, and might be hard to customize, but just send me a PM if you would like to use it, a link-back to one of my games or so would be an amazing trade.
