I really liked the essence of this game, and agree with other comments it's really strong but has a few parts that stood out like the sound fx being repetitive w/o much variation. Overall it's super polished and well crafted!
I really enjoyed this sort-a-thon for the first couple levels, then it started to feel repetitive and slowed down once I got to the BIG room level 3. Kinda wish I Had some magical helpers to auto-sort while i kept manually collecting so it'd go a little quicker. Despite a few sound fx being repetitive, it was also super relaxing and meditative after a while. Especially once I discovered you can carry up to 4 at a time!
The sounds when you complete a shelf 100% are great (๑˘︶˘๑)
Overall i definitely felt hooked till i hit level 3 and it felt like too much to do back to back right after level 2
