A said, ok - a handful of bucks.... why not? I love Digital eel games. The Demo was TOO friggin hard - but hey, anything to support these guys. SO GLAD I BOUGHT IT!!! A lot has changed from soundtrack, music and just plain playability. On the demo - I could not get to level 4 if memory serves me right. Now I am stuck at level 7 and having way more fun playing this. Digital eel Rocks! ;)
