This was pretty fun! I'm looking forward to learning more about the world and what's causing the Hum, why did it suddenly appear, and how can we stop it?
One thing I'd like to see adjusted in the game is a little bit of an easier time seeing things. I spent a few minutes wandering looking for stuff like the coins, it might be nice if they're a little brighter or have some sort of effect to make them more visible
Great job though, keep it up and can't wait to see more!
