Cuphead officially launched on Steam ahead of the weekend and so far has been doing splendidly well. In fact, it might just have the strength to topple some big hitters that released in the same week.

According to SteamSpy, a third-party platform that monitors and analyzes data, the game has so far sold more than 125,000 copies on the digital distribution platform. This figure is unofficial but tells an impressive tale for a new entry in the market. Take note that sales from Xbox One and PC through the Windows Store have not been included, which makes the overall sales much higher.

At the time of writing, Cuphead is second in the top sellers list of Steam and just behind PlayerUnknown’s Battlegrounds. At the time of launch, the game was behind Total War: Warhammer II and Divinity: Original Sin 2, both of which are excellent games. It has taken Cuphead only four days to jump over them to take the lead.

The retro run-and-gun platformer, featuring visuals inspired by the works of 1930s cartoonists, has been receiving stellar reviews from every major publication. The gameplay is challenging and may throw some people off, but will force players to blister their thumbs nonetheless. Cuphead is undoubtedly a marvelous work of art from indie developer Studio MDHR.

Cuphead is currently available for just $20 on Xbox One and PC. That is a cheap price tag for something so good. This is one game that PlayStation 4 will have to miss out on. For the time being, the game remains console exclusive to Microsoft. We will see next year if that stance is likely to change for Sony.
