Hello, I am curious about decker. It's like a copy of Hypercard, but is it meant to stay that way ? I mean, dithered and black and white ? Or is that just a design choice on itch?  I would love to play around with this, but the old-fashioned b/w seems to give the intention that this just for fun, and that it is not something that can be used for displaying to somebody who does not know what decker is ? Not certain if I'm conveying the right question/explanation here, my apologies.  

Black and white dithered graphics are the default when you open Decker and many people choose to work within that limitation, but the program does support 16-color palettes and there's been several published color projects.

If you'd like to see a couple of examples from last December's Deck Jam, these two are in color in two different styles:

Fear and Loneliness in Latona's Void and Desker

But also here are two black-and-white games from the same event that have a clear visual style that I think is approachable with-or-without any knowledge of Decker as a program.

The Family Record and Broken Gate (It's retro b&w but very well done)

I don't know if this helps! 🙂But if you have any other specific questions about what it's possible to do visually in the program, I'm sure someone can answer.

There's some discussion of the design philosophy behind Decker's retro aesthetic on this page http://beyondloom.com/blog/responses.html that may shed some light on the reasoning behind it.

In terms of my own work I've found that limitations can be an aid to creativity and helpful in getting me past mental blockers.
