When I try to rebind the controls, the game freezes - the cursor does not move, I cannot close the settings, and have to shut down the game via Task Manager.
Considering how counter-intuitive the default controls are, the bug makes it unplayable.

There were also issues with installation, where the game used the space on the C: (SSD, system) drive during installation, instead of D: (HDD, everything else), where it was to be installed.

I rebinded the gamepad controls and had no issues. And did you choose the D drive prior to downloading the game? Make sure it's the default install directory on the Galaxy settings.
