Please allow changing the controls (keys) of the game.
For example, it’s hard for me to use four keys that aren’t in one row, and pressing n & m at the same time doesn’t always go well either.
If I’m using Vivaldi, it’s some recent Snapshot. I use Artix Linux. You may know me as tiosgz.
If you want to install V-Snapshot on Arch / its derivative, but don’t know how, see https://potmeklecbohdan.vivaldi.net/341/
