So, I've been playing around with a few values in the project that raise the player perspective a little more off the ground and drops the ceiling down to about a third the height in the jam entry and I think I'm starting to get a lot closer to a happy medium where the maze still feels large without making the player feel like a mouse. Luckily, I set things up so I can test stuff like this by just changing a few variables around - which is totally the result of advanced forward thinking game design techniques and not at all dumb luck.
Thanks for playing and all the kind words!
