No it says F or V = Jump
:D
You read the instructions too fast. But yeah if you happen to press Space in the exploration mode, it'll jump even if nowhere it says you jump from Space. :D
The multiple keys is for a certain reason, a friend of mine can't use Space to jump, nor attack either. So need alternative keys for him.
I didn't have time to implement a "Redefine keys" option so that you could bind any keys you want. :)
Thanks for testing it though!
