Tom Vian noted, "While the game hasn't set the world (or our bank account) on fire, it's been a solid success for us". ScreenRant praised the "logical, cleverly designed puzzles", the "distinct, entertaining personalities" of the characters, and  "unexpected twists and turns" of the story. Nintendo World Report described it as "the closest to a brand-new Layton game you're liable to find in 2020". Tangle Tower won the 2020 IndieCade award for Best Performance. Additionally, it was nominated for the 16th IMGA. Untitled sequel (TBA) 
In March 2020, SFB Games announced they were in the process of writing the next entry in the series, which wouldn't be called Tangle Tower 2 as it would be a brand new story with new characters. Soundtracks
