Great idea!
I think 9 seconds is way too little to wrap around what's going on, especially since often things change up[on death and you lose a few seconds just by figuring out what's going on. I'd say you need to give at least 20 seconds or something? Not because you don't have enough time (you do) - just have a breath between the rebirth. Or even having a 3-5 second pause between runs would also help.
Or maybe I'm just too slow and get overwhelmed too fast :)
