some of us began working on our games when the jam was announced (and earlier as this is an annual jam around the same time each year) where this is a completely casual jam with no surprises like waiting for a theme or requirement to be announced (except for the "surprise" extension ;) ).
participants with various levels of experience devote as much time/energy as they can/want toward whatever project they want to work on and share, small to large, while the jam's duration is merely the window to submit our 20 Second game(s).
that said, i've played nearly all the submissions thus far and, while some obviously took more time to create than others, most all deliver a unique FUN and are complete successes that their creators should be proud of, and i look forward to playing yours :)
feel free to share your progress on the 20sGJ Discord Server before it's finalized if you'd like some feedback or just want to tease some of the fun that you've got in store for us :)
