Nice :D Reminds me of "Vignettes" and "Islands: Non-Places", and also of an old obscure game called "Projective" (https://v3.globalgamejam.org/2014/games/projective).
It says there are 19 levels, but there are currently 24, two of which were added after Icely 4-months-old video, so this game is still being worked on. Perhaps the description should be updated.
I have found a couple bugs. In one early level (8? I forget which), one of the walls became white before anything was absorbed into it, but I couldn't reproduce it. In level 20 (the gardening shed), it is possible to absorb the shears before the lawnmower is gone.
Also, could you please make the game downloadable again?
