So there's no real gameplay here, just clicking through dialogs and menus to buy stuff to increase the rate of currency gain... but it is notably punctuated by some MS-Paint tier "drawings" that are laughably terrible in quality... but, kudos to the developer, at least it's not AI slop or pixelcrap. I don't think this is any better than that, but at least it's different.
As mentioned, the graphics aren't great... MS-Paint images and dialogs only, it might as well be a browser game. That will understandably be a turn off for a lot of gamers, and it's a big contributor to the failure of the game to attract gamers despite having no up-front cost. Gaming is a primarily visual medium, and if developers want to succeed, they must understand that it's not an area for compromise. You deserve better than compromises, and Steam isn't here to compete with Chrome and Firefox.
Not every "free" game really is. There's often MTX, or content locked behind DLC, or donations being requested, or any other number of things that could mislead gamers, but in this case I'm glad to say this really does appear to be a fully free game.
Nothing demonstrates a developers belief in themselves and their work than giving it away without any remuneration. This is a service to themselves, and the gaming industry, and should be applauded. Of course, just because something is free, doesn't necessarily mean it's valuable.
Even though this is "free", it failed to appeal to the 120 million+ gamers on Steam. SteamDB showed the game peaked at just a dozen or so concurrent players, and now there's basically nobody playing it. Even though it's free. This is a dismal public reception, but it's easy to see why gamers rejected it.
Bearing in mind that free games don't add +1 to your game collector count, should you bother adding this to your library and downloading it?
Not this time. This isn't worth downloading. While this won't cost you any money, you get what you pay for, and sometimes, even when the game is free, it's still not enough.
