This is almost certainly just a bunch of Unreal Marketplace assets dumped on a basic top down shooter game blueprint with a few turrets thrown in, and rushed quickly off to Google Play because this is a garbage mobile app.
It's not a real TD game like Kingdom Rush, it's just wave survival, so it's even shallower than it looks.
So, the game might look better than you'd expect from an amateur project, but this is because it's almost certainly made up of stock assets, "borrowed" from asset stores and free asset websites. Very little in this game is truly the creation of the "developer", it's just a bunch of rearranged assets.
While there's no up front price for this asset flip, the other problem with asset flips is that when developers aren't capable of doing their job and creating high quality assets, it's also true they can't do any of the rest of the job of a game developer either. That's definitely true for "JUST DEFENSE".
This is a mobile app... it doesn't matter if this was ported to PC before or after the app store release, or even if this didn't even make it to the app stores. This is built for the absolutely lowest of all gaming platforms and must be judged as such... it's not going to give you a cutting edge PC gaming experience. That alone is enough to disqualify this from any recommendation. We don't spend thousands building gaming rigs so that we can pretend they're iPhones and play iPhone games and mobile apps.
Now on to pricing and value for gamers.
This is "free" enough (not every "free" game in the "free" section is truly free, there's usually some hidden price tag), at least you won't be expected to spend any more money after you download this, but just because something is free doesn't mean it's good, and the cost of a game is more than just financial, your time is valuable too.
In terms of public reception, this failed. There's over 130 million unique gamers visiting Steam every month. SteamDB showed the game peaked at [b]only 2 concurrent players[/b]... this is a dismal public reception. This was so bad they couldn't even give it away.
Since free games don't contribute to your game collector badge and other profile stuff, is this a worthwhile addition to your Steam library?
I think you should give this one a miss. Although it's free, your time and storage are valuable resources, and the market is filled with superior options.
