Know what's really shitty? People are going to spend money on this shovelware and feel ripped off.
College unity projects like this belong on itch.io or gamejolt. Not marketed as a Sony exclusive.
All Sony has done is upload the trailer to its YouTube channel. You're acting like it was a State of Play announcement.
To go a little bit further, I don't think the trailer is deceptive. It just shows the game, and I'm sure most people could judge if they'd want to play the game or not from the trailer.
There's also misinformation in your initial description of your presumption of the developer, for one the two involved are new devs from Spain but they aren't fresh out of College either, the whole Playstation Talents program Sony Spain is doing is to support growing the game industry in Spain, and this title won to get the financial support, office space and development hands to help realize it. Alongside this, the actual rules of the program state that teams must be at least three people and separate roles at least, so I take your initial statement as hyperbole based on your personal feelings. These devs aren't cheating or lying or scamming about anything like you seem to be implying, Sony Spain and Sony as a whole opened up specifically a branch and program for projects exactly like this, which was their decision, to help grow and support the game development scene in Spain and help realize small team projects into fruition.
The game will turn out how it turns out, a game existing on a marketplace isn't some blight on the customer or something. There's probably even a small audience for this game. If you're not interested in the game, then just don't buy it. If there was something shady or seedy about this I might understand your position better, but right now you're just coming off as concern gatekeeping.
