I'd say there's a lot of spoilers around: the description, the gifs, arguably even the tooltips are unnecessary. Luckily I finished the game before I noticed any of them. Took about 10-15 minutes. Here's my experience:
Loved the prototype. It doesn't hold your hand, it has this "you'll figure it out approach", a nice fit for its chill, casual style. It's diverse and has a fair share of exceptions and "one time onlys". It encourages experiments and discovery.
The puzzles are all very sensible and logical. It's all "it doesn't fit here, it's missing there", no random clicking all around required, so typical for point-and-click games.
This is exactly the type of game I'd give my kids to play (if I had any, lol). I definitely plan on buying if you release DRM free on itch.
