A good friend sent me this, I've tested it too, it's a truly playable version. It's exactly the same as the official one.
How to run: Control Panel → Regional and Language Options → Then in the language selection, choose Korean. You need to complete the settings to be able to play the game correctly.
Main program KartRider.exe
The operation is simple. Most other racing games have complex controls that prevent many people from fully enjoying them. Additionally, you can experience drifting, which is what we usually call "tail sliding."
The game's controls are also similar to "Bubble Fighter," using the arrow keys for direction, Shift for drift (tail slide), Ctrl to use items, and Alt to switch the order of item usage.
