Oh, release and abandon with this game it seems?
I recently found it and added to wishlist for some future sale, but removing it now!

Oh but there is, the devs posted a solution for this back then.
I know for some people this may be too complicated but hey, I'm an oldschool PC gamer and we all should be happy we don't really have to deal with config.sys and autoexec.bat configurations anymore :-)

Maybe, but they provided a way to change key bindings back then. Here is some more information so no one has to visit this... other... site :-)

Edit input.ini file in folder C:\Users\{username}\AppData\Local\MoonMan\Saved\Config\WindowsNoEditor (it's advisable to make a backup beforehand).
Change it to this: https://pastebin.com/gNXkC4pi
And then make your changes to the bindings.

They made this example for users with AZERTY keyboard layouts: https://pastebin.com/F91qyzqg

So, apparently the "consideration" didn't lead to action. I second any comments that exposed this as simply ridiculous: A game without remappable keys in 2019-2022!

Although I'm right-handed, I'm using the mouse with my left hand, because I prefer the symmetry of the numpad for my key controls.

So, no, I won't be able to enjoy your game. And I refuse to fix your negligence with any third-party tool. No rebinding for us, no money for you. Lose-lose. :-(

edit: I also refuse to edit config files just because you are too lazy and/or ignorant to your player's desires. It's a matter of principle: My money goes to devs that don't behave this way.

This didn't work for me. :(
