Sure, it's got a really weird name (was originally called Wimp: Who Stole My Panties?), but Wimp! Who Stole My Pants? is a solid little puzzler that's now on sale for the not-so-weird price of free!
The goal of Wimp is to help this little blob retrieve his pants. Or panties? The description in iTunes still says panties so who knows. Or cares. With 50 levels and a unique physics system, you won't be worrying about those minute details anyway.
