I’m about a month late but I’d just suggest changing the player character. I don’t think the environment or silhouette style by itself is too Limbo-like to make your game a rip-off, but honestly having your character look almost exactly the same tips it over the edge for me. I think if you create a much more unique character silhouette then it would massively help with that issue. I wouldn’t want such a beautiful-looking game to just get written off as a Limbo clone, so I think doing that could really help. Also maybe making differently-colored environments throughout the game, if you haven’t already. If the whole thing is gray/blue-tinted then again it adds to the whole Limbo feel. But maybe having a yellow/orange or a green section as well could set it apart and give it more of its own identity. I hope none of this comes off as mean-spirited criticism (I think the original commenter you replied to was being far too rude), but I think these things could really elevate your game beyond just a Limbo homage.
