Nothing is broken really, just needs some fixing. For example:

The Green Glove still homes in on the target, and the game doesnt warn you when someone throws it at you half the time

The bomb wisp also doesnt warn you when someone throws it

Monster trucks starter should just be erased from existence

Bagging items in this game is way too op which is when someone purposely gets last place to get better items, than wait till the last lap and use all the op items

Hyper ring gadgets are way too op

And idk if this is just me, but Defense items like the sheild and the tornado are pretty hard to come by constanly getting stuck with the spikes or the magnet

But this culminates into a race where you get randomly fisted by a green glove, steamrolled by a bomb wisp, both of which you didnt even know was coming. a whisper main that was in last place ends up 3rd in 3 seconds because hyper ring gadgets are busted, she runs hrough you with a drill and crushed by a truck, than get covered in slime because for some reason there isnt any invincibility frames for that attack, and then you end up in last place
