I love it! Short and sweet but very captivating.
The art is really nice and nostalgic; plus the color palette is really nice! It blends in really nicely with the music and story that has that 80s/90s touch to it.
I think the biggest thing that would've been nice is having to click around the environment to search; maybe even have Celeste walk to where you click in the area. It'd add the little extra bit of interactivity. But other than that it's really nice!
