The riddle and parkour, maybe reduce the difficulty a bit unless you want suffering (literally a death counter to tell how bad i am). The riddle, maybe because me dum dum, but hints are always welcomed for me (maybe make it optional or after some time). The parkour, very punishing for small errors, AND there is a time limit for certain part. Having one is ok but both is a bit too much i think.
Music sounds good. Nice transition also.
