Controls definitely need to be brushed up on, it's mostly due to the trail being sloped in some areas and the code logic not working well at max speed.
The idea with the obstacles was to make the player take a risk, either give up some points to try and gain more, or just take the safe route and get less points.
Also her hitbox actually is an invisible sphere, it's just a bit smaller than her model. So I could add a second larger sphere just for collecting the food.
