10/10 animations xD love the crouch walk, its the best one!
The ninjas hitbox felt a little thicc along the x axis, I walked into spikes next to me and died thinking I wasn't close enough.
Generally I liked the platforming.
It was nice of you to have the spikes not kill you in the first loop but it would have been nice if you would have had one shorter level in the start instead of making the spikes harmless.
Very charming!
