Works for me as well, but I can't figure out how to save my progress (gaps, etc.), thinking about buying the game but I want to figure this out first
There's message at the start of the game telling if the game can't save in AppData.
Otherwise it should save your gap, color and settings. I'm not entirely sure where it's located on mac, maybe in WineBottler.
On PC it's here: C:\Users\*YOURNAME*\AppData\Roaming\Stencyl\SkateRideDemo
