Thank you for playing, and for the great feedback! I'm glad you liked the concept and the sound design - those are the two things I focused on so it's great to hear they are working.
I'm also very grateful to know about the approachability issues you raised. If you can believe it, the map actually used to be even bigger - I pared it down a couple times during development, but it sounds like I still haven't found the sweet spot for it yet. Regarding the controls, it looks like we're allowed to update the description, so I've tried to clarify them a bit on the game page.
