Peak was a surprise viral hit when it released for PC in June, and it's still consistently in the top 15 most-played Steam games. Like other contemporary indie breakthroughs such as R.E.P.O., Phasmophobia and Abiotic Factor, it kinda came out of nowhere. And also like those previous hits, its success has led to some flagrant clones on Roblox, which is seemingly the go-to place if you want to play a shittier version of almost any commercial game you could name in 2025.
A good example is a Roblox game called Cliff, which is "a challenging climbing game where even the smallest mistake can be your downfall", according to its description. At the time of writing it has over 7,000 active users and 59,173 "favorites" (which are basically bookmarks for Roblox users, and can therefore serve as a proxy for popularity). It's the work of Roblox developer PewStudio, who cites Peak and another game called Mountain Climbing as inspiration. "Special thanks to those amazing creators!" the Cliff description reads.
