@RZK has a great youtube channel full of solution videos for many user-created levels (recent and older levels): Video Solutions https://www.youtube.com/channel/UCL9Zq_NDPegxGOTfK0b82Kg/ Solutions organized by author https://www.youtube.com/channel/UCL9Zq_NDPegxGOTfK0b82Kg/playlists
Spoiler So I don't have to make videos anymore? Sometimes I make my own videos. Because usually only a few players can complete my big/complicated level.
How exhilarating. Yes, indeed, video solutions are needed, especially by new users. On other games, videos are essential and so on this game, where they can see firsthand how level can be solved and direct learning, it's very convenient.
