It’s a rule of the universe that if you release a successful indie game, there will almost immediately be crappy mobile knock-offs and a version built in Roblox. That’s as true as ever for Peak, the adorable co-op climbing game about scaling a mountain with your friends (and sometimes eating them), with a Roblox rip-off called Cliff. And Peak developers Aggro Crab are clearly not impressed.
Peak came out on June 16, and has quickly gone on to be a summer smash. From the developers of 2024’s Another Crab’s Treasure, the indie co-op climbing sim has become massive, peaking at almost 115,000 simultaneous players, and still has 20,000 people playing right now. It’s been a splendid and well-deserved success. So of course, there are knock-offs. But my goodness, Cliff‘s is beyond blatant. And Aggro Crab aren’t delighted about the situation.
“tbh would rather you pirate our game than play this microtransaction-riddled @Roblox slop ripoff,” says a post from Aggro Crab’s official X account, spotted by PCGN.

Cliff, by a developer called PewStudio, is the most obvious copy of Peak. Except of course it instead looks really crap because it’s made in Roblox. To demonstrate this isn’t hyperbole, here are a couple of comparisons. This is Cliff in Roblox:

It’s not exactly subtle. The same goes for how the games play, the floating hands for climbing, the plane crash start with the suitcases on the beach, pretty much everything. Except that in Cliff, everything costs money. From the airport at the start to the suitcases on the beach, the Roblox rip-off wants you spending your Robux as often as possible, because of course it does.
Of course, Aggro Crab would prefer you just paid for your copy of Peak, not least since it’s only $8 in the first place. But seeing their creativity reduced to a cash-in knock-off must be incredibly galling, not least when people could be playing the far superior game for a low up-front fee, and never have to spend another cent.
Oh, and really, no one should be going anywhere near Roblox in the first place.
