Here are my suggestions.
1. Tree skiing. You should put some trees way off to the left and make tree skiing with jumps, gaps, log grinds, pillow lines, etc
2. Urban park. At the bottom or off to the right, you should make a small town with some handrails you can hit, a road gap, and some roof drops.
3. A half pipe gap. I think this has already been mentioned too but you should just put a jump on one side of the half pipe. I spend a decent amount of time trying to get the speed to jump over the half pipe, and it glitches every time I would get close enough.
(Idk if this is too hard, but spawn points would be great (like pressing 1and enter or 2 and enter for different spawn points))
this way, you would include all genres of skiing into the map. Also if you want to make some $, put some advertisements up. I don't really care about them that much and you could even have a pop up for some extra $. Just please don't make the game cost money "for some extra features"
4. Kind of off topic, but a point system would be sick so we can compete with our friends and it only makes the game that much more addicting.
Thanks Malcolm for continuing to update the game and looking at our suggestions.
