I've played some games with some weird controls in this jam, so this one was very refreshing. It feels awesome to drift your cart around at high speeds and ram into your opponent.
I was gonna suggest the same idea as Havudgjj, to have an indicator of where enemies are on the map, but I was also gonna suggest having hitboxes on all sides of the cart so you can ram enemies from any direction. I had a lot of moments where I rammed from behind and it did nothing but when I rammed from the front, it took down my hp instead of the opponent's.
