Bought this game today, and I must say, I am having a blast playing it! I have yet to beat it, but the great thing is, I'm having fun either way, and when I finally do beat it, I'll feel like I earned it. It's challenging, and fun in just the right proportions. I love all the items, and achievements. Well done guys, can't wait to see what you release next!
