I doubt the OP is still looking for an answer to this, but in case any future people are here goes.

Keyboard works, but no mouse support - and it doesn't need it. Definitely better with a gamepad though.

I bought this and some other games yesterday and mixed it up with another game. I thought "Nobody" here was supposed to be like Forager because the main character looks similar. But nope, I was thinking of Nova Worlds.

Nobody Saves the World here is by Juicebox - the guys that did Crashlands. Somewhat similar feel.

Thanks for the warning.
