The first level is a pretty bad first impression. Get past that and you're in for a good time.
i think that is a very interesting and fun time. the trick for bosses is knowing when to i-frame dash and parry. Parrying projectiles drops health, but health drops expire fast! Have to balance going forward and taking your time.

its too bad the parry input is a double tap
it's not like i was accidentally doing it or anything but there were times where i was on beat to parry on the first press, but not the second
if that makes sense

unlimited continues and a short password system makes this pretty forgiving too
