Warning: Third Party Account
This game requires you to create a third party "R2 Games ID" account... there's no valid reason for this in a PC game when SteamWorks is available. This is often done to harvest private data and profile you, with potential sale and transmission of your private data to third parties. The developers will probably argue that you can trust them, but if they were trustworthy they wouldn't demand you create a third party account.
This represents a considerable risk to gamers due to the privacy and security implications of developers that wish to bypass Steam and harvest user data. Remember, sometimes if the product is free, YOU are the product.
Warning: Microtransaction infested mobile app!
This game is infested with a toxic mobile app style cash shop. You will be prompted to and expected to give money to the developers through this cash shop to buy in-game goods so you can play the game.
"Apoclone" is one of thousands of nasty mobile apps infesting the "free" section of Steam, but it's not really free.
This garbage mobile app was so lazily ported the developers didn't even bother changing the 9:16 mobile phone aspect ratio. I remember when mobile app scammers would at least pretend and try to tell us it was rain. Anyway, ignore the garbage "post-apocalyptic strategy RPG", this is a garbage P2W clicker/idler scam.
There's only a superficial game here. The game visuals and the game itself are incredibly shallow... think of them as the too-bright, colourful, thin plastic cabinet dress theme on a poker machine at the casino. That's basically what this is. So really, the mobile app "game" is just a veneer, a thin skin wrapped around a nasty, predatory mobile app cash shop.
Putting that toxic mobile app monetisation aside... this is a mobile app. I didn't spend thousands on a gaming PC so I could pretend it's an iPhone, and I don't think you did either... this kind of mobile app has no place in your Steam library.
Now on to pricing and value for gamers.
In terms of public reception, this failed. There's over 130 million unique gamers visiting Steam every month. SteamDB showed the game peaked at only 8 concurrent players... this is a dismal public reception. This was so bad they couldn't even give it away.
Given that this free title won't increase your game collector count, is it worth your time to add it to your library?
Definitely not... this is just an unethical cash grab. Avoid at all costs.
