I quite like the skiing controls in this, once I figured out how to move properly it really had the flowiness of skiing. I think the game would be quite fun if you expanded on it. Right now, the experience is dampened a lot by the audio, both where it is implemented and where it's lacking. The gun shots get suddenly cut off and are quite loud, the music doesn't loop properly, and there is no other sound whilst skiing so it all feels a bit disconnected.
I'd love to see some particle effects especially when doing curves, and just a bit more to make the snow feel like snow you're skiing through!
Was quite fun to play!
