In the level that you fight a wasp for the first time there is an abyss at the left side that if you fall your character gets stuck (like softlocked) under the screen (you can walk to the right and left until hitting an invisible wall I think), but I had to restart the level to get out of there
Also when I first killed the spider it happened at the same time I got killed by a projectile, after that the screen turned black with the boss music still on, the r key didn't work
Overall this game seems cool! The concept is cool and fun to play (throwing sword->jumping->grabing mid-air and throwing it again was a really cool combo I did with it)
