pretty cool! I also think that the game needs more checkpoints (and some spikes are bugged so when you die by them, you go to the start). There was a lot a care in the animation, but some of the assets were just stretched, you could have used multiple of them to have the same effect (like many chains instead of one big one) and the hitboxes were just unfair, I would sometimes die 20 pixels away from the spikes. i would tweak both the player's hitbox and the obstacles.
The lighting was nice, the powerups were a good idea, and the idle animation was the cherry on top to make it super cute! keep the good work!
