A new Roblox game heavily inspired by Peak, the hot new social game on Steam, has ruffled the feathers of both developers and players alike.

Made by Roblox developer Brazilian Spyder, Steal a Brainrot is a tycoon-like game that tasks players with stealing strange meme-like creatures—the titular Brainrots—from one another.

Mountaineering co-op game Peak already has a Roblox copycat, and developer Aggro Crab isn't taking any hostages with its response.
