I was looking forward to playing this, though only just managed to get it to run. (If anyone’s struggling to run the game, it would crash in Firefox for me but worked on Google Chrome!) I played after your post about the boss’s difficulty update in case that makes any difference, but I wasn’t able to progress from this point:

Heyhey, there is a bug, where if you jump from the third to last platform on the arena, it doesn't activate the boss. I guess you all are pretty skillful, man and skip the last couple of steps (definitely understandable) xD If you hop on it from the last or second to last platform, it should be good and then you'll meet Death!!!! haha, have fun!
Finished the boss fight! Cool design for the boss and a very ominous beam of death. I think the interaction with jumping/landing on the edges of platforms has an issue since I get stuck there. The star’s 8-directional movement makes it hard to aim directly at the boss (sometimes I’m shooting at an angle when I’m trying to face it). I liked that the boss attack patterns were predictable, but it was kind of difficult for me to visually tell whether it was aiming up or down.
