Hi etoile!
Could you tell us why you think the contest could be about scam? Like you, someone else may think so, and we would like to try to avoid giving that image.
I would like to tell you, for the sake of clarification, that this is the 9th time the contest is being held. Although it is the first time that we are doing it through itch.io. To give more details, it is hosted by a recognized entity such as the University of Alicante. The official contest rules signed by the university are here https://www.boua.ua.es/Acuerdos/DescargarAcuerdo/16921.
Here is a video where you can take a look at the awards ceremony of last year's contest so you can get to know the contest a little bit better. https://youtu.be/znL7Yfbv94E
Also check out the official twitter account of the contest where we put all the information and the hashtag #CPCRetroDev where people upload images of the games they are making. I'm sure you'll be surprised by the quality they have for 8-bit games.
#CPCRetroDev was born as an educational project, where students can learn to code in assembly language. The current assembly and Amstrad's are not so different, so it is a very useful space to learn. Also, competing with professional game devs for prizes motivates students to make better games and prepares them for the professional working world.
For more information, you can check our website, where you will find all the information about the contest and all the games submitted in the previous editions. And of course you are invited to participate in the #CPCRetroDev, create a game and learn a lot from the Amstrad Scene, because this is an amazing world!
