Bought this on steam, it's really cool! However, I'm really confused by the map. I can't tell how high up or far down I am and I've gotten lost. A compass would also be really useful for finding my director if there isn't one I haven't found yet. Finally, being able to close up holes I made that go nowhere would be very helpful, including ones that go too far down and require me to either dig back out or respawn.
I understand if you're not interested in changing these because the game is feature-complete, though.
