I wouldn't consider it very similar honestly, but for those who play it, definitely use a walkthrough if you want to complete as many paths in it as possible because it's otherwise easy to make a single choice that boxes you out of many other possibilities. I learned that the hard way (expending large amounts of time replaying it until I gave up) and have not wound up opting to re-download it and use said walkthroughs. So again, definitely use one!
