Hoobs, you should be able to get those scratches removed at certain video rental stores for just a few dollars.
There's one near me that does this with a machine for just 3.00
Shape Shifter... yeah it can be irritating at times but, over all it's a lot of fun if you like action/adventure side scrollers.
It's a little like Legendary Axe and a little like Rastan except that you get the power to turn in to other creatures every time you free one of the ancient wizards.
The falling off of the ledges thing will piss you off more times than you care to count.
It's worse when you're the Shadow Cat and even worse as the Rock Creature but, if you can stay calm, focused and power up in the right order, you'll eventually get through it.
I've only beaten it once and that was probably back in the mid '90s and as much fun as it can be, as nice as the graphics, music and voice acting is, this game will really test your patience.
