ok the boss is now updated, hopefully it's less frustrating now. try it out! :]
I tried out the boss again, and god, it feels way more in my hands. When i fell off i didn't get upset that i misunderstood the physics, but rather felt like it was a fair challenge. You definitively succeeded here.
Phew, I'm SO relieved to hear that! Once again, thanks for your critique, it really pushed me to make it a much fairer first boss. Cheers!
