It’s tough to say considering that there are so many places where you can make a mistake and end up returning to the last checkpoint. One piece of wisdom that we have is that you will need to set aside a large chunk of time if you intend to beat Big Flappy Tower Tiny Square in one sitting. Even the best speedrunners take roughly 30 minutes to 1 hour. We expect that it will take beginners around 2 hours to complete the game, although it might even take longer if the Big Tower Tiny Square series is new to you.
