Thank you for playing! A minimap might also be useful for showing where guards are patrolling, I think they're actually very easy to do in Unity with the layer settings on cameras but I'm still very much a novice with cameras in general. Something to think about, thank you!
I didn't realize there were so many vertical gaps which could be snuck underneath. I had to go back and check, it's most of them! It''s pretty embarrassing, thank you for calling my attention to it. Probably all I had to do was sink the walls a bit past the floor... another thing on my list of post-jam fixes! :)
