Winter!: Prepare for holiday gaming!
For those who doesn't know what this challenge is, basically, you come from the left and you have to get the artifact on the right side of the block, right where I stand now.
The only problem is that in order to get from left to right, you have to fly seven screens up and then all the way down in one try without any pause.
Sounds easy. Took me almost three hours to get it right.
