Bought years ago and tried several times to get into it but it just never gels with me, so I'm going to draw a line under it now.
I love the style, I think its more interesting shadowplay then limbo, the controls are fine (and works well on steam deck in spite of not being verified for it). But it all just feels a bit heavy sluggish and uninteresting, not just in platforming but story too.
Its one of those games that chances are you already have a more interesting and joyful platformer available to you now, that I (or you) would be better off playing, even ones I've beat I think I'd rather replay then continue playing this, like Ori or Dust or any of the Mario games, just to remember what joy feels like in playing a game.
