Thanks for the comment Virtual Nomad,
To answer your request, I live the world of autism from the inside so I simply observed the interaction that autistic people have with devices and computers, adding details that make it possible for them to use the software as well.
Trivially "Puzzle Classic" was born because I could not find a single puzzle game suitable for autistic people: expensive, full of advertising, complex and unclear graphical interfaces (for them), music and effects are not suitable.
To give you an example, in "Puzzle Classic" a fundamental point is the autonomy in starting the game and restarting it: it was enough to insert the animation of the play button that captures the attention and allows this autonomy.
Another example: during the game often and willingly, autistic people who use the games present on the various marketplaces, involuntarily press buttons on the screen that interrupt the game (preferences, return to the menu, etc. etc.). In "Puzzle Classic" I bypassed the problem by using the classic prolonged pressure of the keys which in any case warns you visually to keep it pressed; this precaution avoids the involuntary interruption of the game.
These are just a few examples.
I plan to create the "Making of" page, so that I can share the guidelines I used in "Puzzle Classic".
If you want to participate in "Andy's Project" you are welcome, you are all welcome!
Thank you
Armando
