Unpleasant Horse is the first iOS game put together by a division of the developer PopCap Games, the folks behind hits like Bejeweled and Plants vs. Zombies. The app was originally rejected due to some violent content, but it's back on the App Store, rated appropriately and ready for a free download right now.
The game was put together in a 24-hour game jam session, and as much as it pains me to say this about a game essentially put together by PopCap developers, this rushed development schedule shows in Unpleasant Horse. You play a horse jumping through the clouds with a few wrinkles in gameplay, like "pleasant horses" that you need to drag down as far as possible to earn points, or birds that give you an extra mid-air jump. It's all pretty straightforward -- you jump from cloud to cloud for as long as you can. I'd like to say the game feels like Tiny Wings, but it's not quite that elegant, despite some colorful art. There are no real extras either, with no other game modes and no Game Center integration.
Still, PopCap started 4th & Battery because it wanted to experiment with some edgier ideas, and since the game is being given away as a universal version for free, I can't really complain too much. Here's hoping PopCap finds what it set out to find with 4th & Battery, and then gets back to making the well-crafted games that it's known for.
