Beatifull! Very good graphic and atmoshpere, and implementation of idea is just right. Atmosphere remineded me for level Abyss from Hollow Knight, and thats my favourite location. Dash mechanic is cool, but you need some time to understand how to use it, because sometimes you just dont understand how to controll direction of it. You could add some more levels for it and it will be very good platformer to publish.
Oh, and I forgot - sound was really good, you worked on it well.
P.S Please rate our game too, we were working really hard on it
