For a second after starting it up I thought I was supposed to enter the individual dots and dashes as the beat hit the end of the line, not the full sequence between beats, haha.
Not sure how you're supposed to get past spikes if they change every beat but you can only move once square a beat, you're going to get caught in them either way.
All in all, a bit fast paced and unforgiving so I didn't get far but interesting use of the prompt
