Fantastic game! One quality-of-life request: if I've got a movement key held down, stop me automatically when a new enemy comes into view. It would make a big difference, especially with the short view distance in hallways and how important a single move can be.
Edit: Something else I just realized...the red "focusing" aura appears a bit later on the enemies than I'd like. More than once I've been in a hallway and an enemy appears, I see where they're at (or on the way to), then I hit my movement key, and THEN the red aura appears. If there's any way to make it show up sooner, maybe while they're in motion to their destination square, I think readability would be improved. This *may* be specific to enemies just coming into view. I'll try to pay attention and see if that's the case.
