Very unique and fun game!! I wish you provided a download link as the web version had a weird glitch where my mouse movement would randomly go crazy and spin me around in a random direction. (I think this happens whenever the game has stutters, as this happened to my last 3D web game and I "fixed" it by implementing a mouse movement per frame cap.)
I really wish the map drawing could have been done in game, but that is prob way out of scope as you would have to like remake a simple version of paint in your game.
Here's the map I made! I loved the non-Euclidian space, really made it a lot more complex!
