I think it's a special thing of south east asian people to hype things as much.
On the other side nobody has cared about western region players since the end of NAKR. So this skill gap was predictable.
The only thing you could do now is advertising the comeback of (the real) Kartrider in western regions!

Yes, the cloud, "1. rocket" and the devil seem to be removed, as well as the triple banana (the giant banana was just awful)
Big failure to remove them!
I'm missing the option to throw the banana in front like in NAKR and Popkart...

The personal shield should defend from everything as long as it's active instead of the first attac only.

Why isn't there friendly fire in item team mode any longer? This was really usefull in team strategy behavior --> clever acting

Now as I tried the upgrade tool you have to write a manual and/or infoboxes what is the meaning of anything.
Firstable you should make clear that each kart is the same just with a different skin (if you want them to be that way).
There should be a clear message that if you spend e.g. 6000 lucci you have a chance of 50% to get 10 upgrade gearwheels and the other 50% to get nothing instead of "a chance to reach the next lkart evel"
It's a hard decission to do this in general...

And it's wired that I should pay a lot of lucci to get used upgrade gearwheels back of the kart.
If you want it that way, you should set a max. amount of 20% of the lucci you already spent to upgrade the kart.
