I liked the dash. When I was playing, I wished there was some warning before it turned red. I think it matches the theme well and makes me think of childhood playing this game in real life.
I agree- I made it pretty lenient with detection (red light movement detection thing doesn't activate until 0.3 seconds or so after it visibly turns red). I was planning to do a sound effect or a flickering animation or something, but ended up not having the time for it.
