my highscore ended up being 61 on like my 10th run or so, although i played for much longer after that without ever reaching over 50 again. i tried using the whole platform to dodge, but it still sometimes felt really unfair when the blade changes directions while directly above you and your crouch ends automatically. interestingly, i never had this problem when jumping over the blade even though these two things should behave the same way...
anyways, i really enjoyed the atmosphere and i did genuinely jump each time my head got cut off.
