The single mechanic of todays "BEGINNER CODING" version delivers an enjoyable experience of gameplay.

Whilst the player interacts with the game as less as possible, a construct of methods provides rules and various theories - impacting worthwhile experience - engaging enough to entertain a player: click 'Go', the green flag above the window (not the 'area' in the game), activate a single sequence of 30 seconds, but time never stops.
Do You finally produce an influence, a satisfying experience that feels balanced, transition well to spice up?

Lets break it down into main game mechanics here to stay.

And here are my appreciations about OMG-jam-6 'Play in browser (9)' Platform submissions (Cards, Campfire, Cartography):

To be continued.

Now, less than one year later.

The team stays following:

« we have changed our tune from "The One Mechanic Game Jam" to "The Outbreak Mitigation Game Jam" »

This means, that I have to find another jam to continue the "BEGINNER CODING" approach.

But today, the One Mechanic Game Jam actually seems to be back.

Here are my appreciations about OMG-jam-8 'Play in browser (11)' Platform submissions (RECYCLE):
