"ProjectM : Dream" is not a game. It's an advertisement for a product called "EVR". EVR is n't even released yet, but it's for a hentai game... which is besides the point, this isn't a game, it's a non-interactive advert where you look at a 3D NPC. That's all you do in this advert, look at an NPC.
This is only free in the same way that adverts on Youtube and banner ads in your browser are. This is a game demo that's been dumped on Steam to advertise another Steam store page in the hopes of raking in some cash. Just because advertisements are free, doesn't mean they're worth your time.
It's important to understand there's a formal process to create a demo/page for a game which hasn't been followed here:

While it might seem like an inocuous mistake, publishing demos and advertisements as if they are full games is misleading and in some ways harmful. This advertisement is taking up marketing space and visibility that would be better made available to a developer that's done the right thing and created a full game. Instead, that visibility is given over to a demo/advert that's been published incorrectly and is polluting the marketplace.
It's unclear if this mistake was made through incompetence or a deliberate intent to mislead gamers. Often developers may choose to incorrectly publish demo/advertisements as separate games as a cheap way to bypass paying Valve for marketing presence on the Steam front page, which may seem clever to them, but it's harmful behaviour and it's not good for gamers.
Even though this is "free", it failed to appeal to the 120 million+ gamers on Steam. SteamDB showed the game peaked at only 12 concurrent players... this is a dismal public reception. This was so bad they couldn't even give it away.
It's important to note that, despite this being such a low quality product, there's a number of positive reviews that all appeared immediately after the game launched, from suspiciously inactive Steam accounts that have reviewed almost no other games apart from this. Take the review score of this game with a grain of salt.
Advertisements and incorrectly published demos don't add +1 to your game collector count, they aren't full games. It's impossible for me to recommend this incorrectly published advertising spam to gamers, you deserve better than adverts.
