You crazy? Disappointed? If it’s not up your alley, you’re perfectly within a reason to not playing it. I’d buy it even then just to complete my Nitrome collection but it’s a different reasoning behind it. Luckily, I love the game. Especially when I finally beat a level I’ve been struggling with. It’s so satisfying. So, everything’s just fine. Trust me, with your purchase history you’re the last person who’d need to explain himself for refunding something. So, don’t worry about it!
