That is true! I see a lot of people that do that.
It'd be nice to have something that's actually playable over however long it takes to make the game.
I was thinking about having a demo. So, there'd be devlogs, and eventually a playable demo so people can experience the idea! It's just a thought.
I feel like a devlog for the same game would get a bit boring after the 20th one, hahah...
