Ah, ok! Yeah, these planks are almost invisible against the floor... Maybe have the floor be a different shade than the planks? Also, it may be helpful to make sure the planks you knock over work more like a hinge than a classic physics object... I knocked over another plank that looked like it was helpful, and it yeeted itself behind the bookcase lol
But still, great game! Also, I don't think I mentioned it in the last comment, but your animations are also awesome!
