Great constructive criticism:
-I was planning on adding clothes removal as HP indicator (3 hits before game over)
-for getting stuck, all the scenes respond to the Escape key, either by going to previous scene or showing a menu
-a boss stage has 9 hits on health, while the animation for the next stage is played the boss takes no damage, so to defeat a boss you need to pass the 3 stages so the health is at least 27 hits
-for bugs I am only aware of the dash frame remaining instead of idle
-for game flow I could minimize the boss's attack timing
