I suggest adding something more unique to the map with obstacles. For example, rolling snowballs when going uphill or avoiding bumping into stalagmites made of ice. By adding a cave, we can have falling icicles/stalactites to avoid and shadows will help the player to avoid them like the Ring of Garfat. We could have an area where some the platform breaks apart and have to avoid falling. My last idea is that on a more thinner road, there would be winds and you have to steer more towards those winds to not slip off.
