Continue working to get to a second prototype.
Let’s get through another design loop today! You’ll want to get the core elements of your game together in whatever is their final format, for another round of testing.
If you are making an analog game, you should have all of your board and pieces made in an initial format.
If you are making a digital game, you should have some playable version of your game available on your platform of choice that you or someone else can play through. The game might not have final artwork, sounds, or even complete levels, but you should make sure your core mechanic is working, and that you can test that mechanic with someone.
