I went to ski yesterday (true story). This is EXACTLY what happened (very true story).
Managed 4759 after getting into the SkiFree zone. The trick is to hit the snow dunes (there's probably a proper term for that?) every once in a while to keep the speed down.
The snowstorms/clouds are a neat idea for obscuring visibility and, while initially a tad annoying, do create a compelling challenge.
The graphics are stylishly retro. The audio fits the visuals, but doesn't really do anything out of the ordinary.
Overall: 7 (Good)
Graphics: 7 (Good)
Audio: 5 (Average)
Gameplay: 8 (Great)
Originality: 6 (Above average)
Theme: 7 (Good)
I liked it, thought the difficulty was about right, this style of game needs to be hard to make it interesting. Brought back fond memories of playing an old c64 skiing game (slalom). I would have liked some lines to better mark the path area and keeping up your best high score (and or an online scoreboard) would have been fun to give you an incentive to try and beat your best run so far. Some suitably retro music would have been nice too. Bonus points for using your own framework.
