The game looks nice and the basics are there, but it lacks the minor things that make games feel good to play. I didn't notice any coyote time, double jump after not jumping does almost nothing, camera moves too fast after switching directions, the player sticks to the walls, the jump height is much much higher when pressed twice in quick succesion, the dialogue repeats after every death.
I hope my little bit more critical feedback can help you improve your future games.
The web build still crashes on the bossfight.
Out of curiosity, why was the game submitted by 6 people, but only 5 are listed?
