The replay value is huge, since the game is all about trial and error. You'll die a lot, but you'll learn from your mistakes, and each time you'll get a little further. It's so satisfying, finally beating the game after all those attempts.
Plus, the game is relatively short, so you can play through it in one sitting, but you'll want to play again and again, just to see if you can do it faster or better. It's super addictive!
