Now this was a fun game. The challenge was pretty intense in the end. I didn't see my exact death count but I beat it at around 595 deaths in one playthrough. I don't know if the double route with invisible blocks was intentional but I found the top one a whole lot easier than the bottom staircase route. Besides that little note I think the only real thing to improve is have your death count/time show at the end of the credits. The game is so intense I never really found myself looking up there except at my death count occasionally.
After I beat the game I went back and tried to give up option just to see what would happen and I must admit, I lol'd. I have a never give up nature when it comes to my games and I set out to meet every goal, so there was no way that I'd stop trying. I could probably cut my death rate to half or even 2/3s if I did a second run now that I've been through the stages several times.
