Furi Demake, an 8-bit mini game inspired by iconic 2016 action game Furi, is about to become a paid game on Steam after over a year of being free. The developer explained that the move to a paid game will help the game increase its visibility, as well as test interest for potential expansion of the retro demake.

In a recent Steam news update, the team behind Furi Demake announced that fans would have until June 23 to grab the game for free, at which point it would become a paid game. “Unfortunately a free game can only enter a limited amount of fests or events on Steam,” the update explained, saying that the demake hadn’t been getting as much visibility as initially hoped. “Making it paid will allow us to register it in events, discount it, and make it visible to more people.”

In addition to this, making the game paid will be a way of testing demand for the retro-styled game, potentially allowing Furi Demake to expand to include other Furi bosses. At present, the demake only includes Furi’s first boss fight, The Chain.

Furi is a fast-paced arcade-style action game by The Game Bakers that blends sword-fighting and shooting in a series of punishing boss battles. The studio teamed up with solo developer Sylph for the 8-bit demake, which reimagined the game’s first boss fight, and released it for free as a “love letter to [Furi’s] community.”

Now, it looks like The Game Bakers want to do more with the retro proof-of-concept, but at least they’ve given fans plenty of warning before putting the price up. You can grab Furi Demake – The Chain for free on Steam until June 23.
