Loved the atmosphere of this! Very clear controls, I think the only time I tripped up was with the dash, for some reason I couldn't get that it activates on spacebar release and you charge it by holding spacebar (but that was more me being a brainlet, really).
Story worked well with the game I thought, the christmas theming and the tree ending gave it that wholesome quality that was already mentioned in another comment. I think this type of story probably lends itself better to an underwater exploration game than something less comfy, I dunno.
