Very addicting game. Took me 800 seconds to get through both levels, but now I feel I could do them first try. Seems very speedrun-able.
Some times the jumping felt like it was not registering as I was running out the platform, probably because I was out of the platform for a few frames before pressing the jumping button. I think the Celeste devs talked about a way they used to combat that feeling
And it all worked great with the theme. Good job!
