Meanwhile, Wohlwend mocked up a 2D course in grayscale, with humps of mountains. He originally designed the visuals such that there would be nothing on the screen where the player had not painted, which was later cut. After seeing Boxleiter's draft, he used crisp colors to make distinct gate markers and made the foreground highly contrast with the background. Their early drafts had a nighttime theme and included an aurora that was later cut due to difficulty of implementation in Flash. Wohlwend left the character design for last as his "weak point". Boxleiter was particularly inspired by the idea of a skier replacing the snowmobile, and set up the parallax scrolling and motion blur, which made the skier appear to go faster. He also added the "tunnel" idea as a series of gates. They animated the skier, who they gave an "ego-tastic" large head on a stick figure body, and decided to not use tutorials, opting for a game that began with the player's first click. Wohlwend's rainbow trail effect was added as a scarf or cape (which later became a rainbow burst behind the player), and the scoring mechanics were refined to reward players who took risks by letting the skier fly through the air without touching the screen. This was partly inspired by the Tony Hawk's Pro Skater series. The title refers to a combination of solipsism and skiing.
