As a remake this game is truly amazing. I love it. I love the challenge rooms and everything. Though (and I know it wasn't in the original) I wish I could jump. Not a lot, just a little. I hate having to grapple swing over teeny crack. Seems a bit much.
Also, would it have killed them to include the original as so many new remakes do?
Deffinetly worth the money and worth the time. It is a great deal of fun!
