Well I just came across a fun side-scrolling arcade shooter called Platypus. This game came out a couple of weeks ago, but I didn't see anything about it in the forums. I personally had never heard of this game until I ran across this on a website, but it was a port from a hugely successful Mac game. All the animations are molded out of clay and you control your ship by using the accelerometer. You can pick up upgrades along the way. I played this game for about 20 minutes and I love it. I would highly recommend this game to everyone that loves arcade shooters.
