This was a short but very cool and polished demo! I really love the color palette and aesthetics going on here. I also love the style of the characters' voices--I'm assuming they must be edited gibberish(?) voice clips of some kind? The cartography is simple but fun, and I can see it scaling well to a larger experience!
I think my only feedback is that some key rebinding would be nice (not that I would expect this on an early demo!); it's a little awkward to have up arrow be look up and space be jump, and the I key isn't particularly convenient to press.
But other than that I'm really looking forward to finding out more about this little world and our pumpkin cartographer! I'll be keeping an eye on this one. :)
