What a comment, thank you for all these feedback.
I totally agree with you about the tutorial, and the idea you proposes to reduce the plates seems like the way to go.
It was an hard choice, but maybe not a wise one, that we used this short amount of time on the deepness of the game(artefacts, cards, monsters) rather than on a tutorial.
This ambitious choice came from the fact that we wanted to make a game with a scale that could go beyond the specter of this gamejam. As you noticed it.
We were just simply not good enough to design and code in time, something that would onboard people correctly, with a game of this scale. We will definetly work to improve on that point in the future.
Thanks again, have a nice day !
