Here's another day-and-date release for you -- Volcano Escape is brand new on the App Store today, and it's an interesting take on the Canabalt-style genre. It asks you to run up a series of platforms inside a volcano rather than across rooftops like usual. The controls are a little floaty, unfortunately, but I think it's designed that way, as you can basically double and wall jump your way up the various stages. There's a button for shooting, and shooting various enemies will turn them into stone that you can then jump off of on your way up. Aiming is pretty tough, though, so sometimes it's easier to just dodge the baddies and move on.
You can also get access to power-ups as you run, and your progress is constantly marked in the game, so you're often just trying to beat your last record. There's Game Center integration for leaderboards and achievements, and you can submit scores to Facebook and Twitter to brag about a particularly good run if you can pull one off.
Things aren't quite as polished as they could be (I still love Monster Dash for this type of gameplay), but the idea of adding vertical platforming to the mix is a good one, and hopefully, it will spawn a little more innovation in titles like this. Volcano Escape, as I said, is brand new and available on the App Store for US$1.99.
