I had a BLAST getting the achievement. I can understand your frustration because it was for the winter achievements, but I've been so bored with all these other easy peasy ones for the other games. Most of them are just a chore. What's the point of even having achievements if they only take 5 minutes to get? The developers already have our money. I wish they were all this challenging.
If anything, I'm mad at the Binding of Isaac achievement. I've put 5 hours into that games since the winter sale and I still can't find that stupid boss because it's completely random. SMB, on the other hand only took me 3 hours and a sore wrist.
