The game is great, no denying that. It is quite short and easy though and being a remake of a very old game, I am not so sure the asking price is the right price, but that is up to you to decide.
One thing that is a real problem however, despite the asking price, is the at times bad performance from the game. It hitches and slows down during gameplay and it is quite noticeable. For a game that looks as beautiful as it does, I wish it played smoother and more consistent. When it plays at full fps, it is a real treat, but it tanks often enough to detract from its polish, unfortunately.
