Thanks! You pick up the items from the rainbow boxes, I forget to include that in my game manual. Some of them have to be locked on to a NPC racer in front of you and it's not super clear in the game right now about that, so that's very possibly what's going on lol. I think with some good UI and a tutorial I can clear that up.
I'll look at that, I thought it was dragging behind a bit but I can definitely put that as a setting in the final game to make it editable how much it's following.
