Cute game!
It reminds me of ascii-games like the original dwarf fortress, with the monochromatic black background and the monochromatic symbols for each space.
The duck walking looks and sounds very cute.
The puzzles, as far as I can tell, are well executed and interesting. The "looping" isnt really looping, imho, it is rather pulling things like balls out of the loop to use them later - or use them one loop later, whatever. I think it fits the theme anyway, no matter the interpretation.
It's a nice game, thank you for creating it.
