As this year comes to an end, we tend to look back on our most memorable events before welcoming the new year. Today, Nintendo America looked back on their successful year and revealed their best-selling indie titles for 2021 in a short video posted on Twitter and YouTube.

With 15 indie titles mentioned, it’s safe to say that Nintendo Indie World had a very successful year. Here are some notable mentions from Nintendo’s video:
