In 2020, Helltaker appeared out of nowhere and quickly became a massive indie success. Part of it is due to clever puzzle design, but perhaps the component of success was the art design and the characters.
To this day, people are making tonnes of new fan art of the Helltaker demon girls and keeping its unique universe alive.
The newest fan creation goes far beyond this, however, as Kyo-hei took it upon themselves to create an entire fighting game based on the original game.
Titled Hellversus, not much is known about it just yet, but the previous make it look surprisingly promising for a 2D indie fighter.
