Are you playing on mobile? This game is not really targetted for mobile devices.
I doubt I will find time for this, but will think about it.
No, but I'm playing on a laptop without a mouse, so it's pretty inconvenient to use some controls
It's because your handler for right-click is wrong, it doesn't work correctly on trackpads (eg many laptops, depends on the driver). This is a well-known problem in Unity input that it's easy to get wrong (due to poor docs from Unity).
Thanks for pointing that out, I wasn't aware of this issue.
Should be fixed before full release.
