Ah look someone who learned about Steam Charts but doesn't understand what consecutive players means. That's not 6,730 players total today, it's showing the peaks of when the game has the most players all in-game at once, you know not everyone plays at the same time each day, yeah? The game has had more than 135k players total.
Also, this is gonna blow your mind, but the game isn't just on Steam.
or putting more effort into the physics/ actual new tricks?
You mean like.. exactly what they did a ton of with Season 2?
Oh btw: 6,141 is 4.55% of 134,901. Which, going by your inaccurate reading of the chart, would be a 95.45% drop, not 98%. If you're gonna pull out statistics and then double-down on them, at least get the number right.
