No revenue estimate for GOG — its rating/review counts don't calibrate to sales the way Steam's do. The Steam version is estimated at $42.6K — a different platform, not this one.

HyperParasite

Your Enemies Are Your Extra Lives! A new menace has appeared to a war-torn planet Earth, and this time the threat is global: a parasitic alien organism that can possess humans and use their abilities to wreak unfathomable havoc. No one knows the whereabouts of this dangerous invader except you… because YOU are the HyperParasite! HyperParasite is a relentless top-down twin-stick shooter that’s different every time you play it. Your ability to discard one human host and take control of another means that the possibilities are practically limitless—each character type has different strengths, weaknesses, capabilities and weapons. Features Players can inhabit any of 60 different human hosts and use their weapons / special abilities! Multiple character classes with different stats! Procedurally generated levels with different gameplay objectives and secrets, ensuring high replayability! Shared-screen 2P cooperative gameplay! Nostalgic 3D pixelated art style with absurdly bright neon colors! Set in a world inspired by the roaring ’80s with a dash of dystopia!
