That will come in time, right now he's just working on mechanics and other such things. Story, Tutorial, all that comes later.
Oh, story? Looks like it's gonna be more "arcadey" so to speak, but cool! Also, was curious if you knew, do you have any idea if there will be a size limit to the characters and if you can permanently stay at certain sizes as you go? Because from what I found all the ways to grow are temporary. Maybe that's what the essence is for but, again I couldn't get that to work sadly.
