Want to use the arrow keys? Try this

[Speedrazor]

I created an input.ini file that allows me to move around with the arrow keys.

The part at the bottom below the blank line is the part I changed to make the arrow keys work.
Normally, the up and down arrow keys tilt the camera, but you can now use the W and S keys to do this.
I also changed other inputs to match my preferences, such as jumping and interacting. You can change those to whatever you prefer.

You can most likely find the input.ini file in the following folder:
C:\Users\*username*\AppData\Local\Hotta\Saved_Steam\Config\WindowsNoEditor
You might have to enable "Show Hidden Items" to find this folder.

Don't forget to change the file to Read-only after you save the file.
My original input.ini file was empty. But just make sure you make a backup of the original input.ini file.

You can no longer change key bindings in the game because the file is read-only. You need to change them in the input.ini file whenever you want to tweak some settings.

I can't guarantee it will work for everyone, but it seems to work for me.
