Warning: Asset Flip!
Gold Miner is an asset flip, what Valve calls a "fake game". The "developer", anyccledev (this guy uses a bunch of different accounts for his asset flips. "freeanygame" etc), took the
Gold Miner HTML5 Game Template tutorial/demo/game asset pack from the real developers, Muscle-SS, changed the name, and dumped the result onto Steam. They're attempting to scam people into buying this, so they can get your money for someone else's work.
The products that result from asset flips aren't "real" games. They lack depth and content, because they're just simplistic copies of demos or tutorials. In this case, "Gold Miner HTML5 Game Template" is just a simple Construct2/HTML5 mobile "gold miner" app template, and doesn't have any merit as a proper, fully fledged PC game, so a copy+paste of it can't be recommended.
Asset flips don't involve any professional game development. Sure, sometimes they may change a few cosmetic things, swap out different assets etc, but at heart it's functionally identical to the asset they're ripping off.
Asset flips like this are harmful to the gaming industry and to Steam because they reduce the visibility that sincerely made indie games should have, and make it harder for gamers to find real games from genuine developers.
Don't reward this morally bankrupt, unethical behaviour from anyccledev.
