For a Worms game, this is oddly the cutest entry of the lot.
From the cutesy theme in the title to how happy all the worms are playing a nice game of golf instead of, you know... Trying to blow each other up like they normally spend their time doing.. It is an odd change of pace, but that doesn't make it bad.. I found this game rather charming, really.
Worms Crazy Golf is a game that takes the classic Worms system and combines it with golf to make a rather strange, if interesting, hybrid of 2D golf sim, where players try their best to smack a ball all the way to the hole in as few hits as possible, while trying to avoid more Wormish hazards such as mines, sheep, and even grumpy grannies, in time earning items that help make getting that tricky hole-in-one easier.
A game about 2D golf might not seem all that interesting at first, but once you give it a wack you find a humble pleasure playing this simple little game. Sadly, as fun as it can be at times, it does suffer from a flaw or two that holds it back from being a rather enjoyable game in the long run.
For 10 dollars, the content the game packs is rather meh, a decent player able to beat the game in a few hours. It might have some form of replay value, but it is rather humble in that area.
To make matters worst, the game suffers from an awkward balancing issue, being that one of the powers (Reverse Gravity) is by far the most broken item in the game. Upon earning it for the first time, it doesn't take a player long to realise that he can abuse it to get easy holes in one for EVERY course in the game.. I am serious about that, it takes all challege out of a nice little golf game, so if you are the kind of person who seeks a challenge, I suggest you avoid using it if you don't want to spoil your fun. For the egotist, however, it certainly does satisfy the desire for easy glory.
I suggest you wait for the game to go on sale for 5 bucks or so before getting the game. It is fun and all, but clearly not worth the current price offered.
