Some of our users reported a bug with the Xbox One Controller in Windows 10 that forces the player to move right all the time, seems that the problem is the latest controller driver.

Windows 10 comes with a newer driver dated July 2015 that supports the Xbox button for accessing the Game bar inside games (to take screenshots and use the DVR feature, etc). However, this driver has the annoying bug that causes characters to move to the left in a small number of games (Including Flat Kingdom).

You can solve this by uninstalling the driver and installing the original Xbox One driver from May 2014, however you will loose compatibly with the Xbox Button.

Please try to do the next steps:

- Have the Xbox One controller plugged in
- Startup the installer .msi
- Deinstall (remove) the current driver, if the installer gives you that option. Afterwards, restart the installer
- Install the driver (keep controller plugged in)
- When the driver is installed, you might notice that the controller still doesn't work
- Unplug and replug your Xbox One controller, it should vibrate

Flat should stop moving right after this.
