I hate to simply reiterate what everyone else has said, but I really didn't understand what was going. So I went to check out your devlog and you said you didn't include a tutorial because people would figure it out because its only point and click and its cards. I think this may be a case of you having made the game so you understand every little thing very well but not realizing those on the outside don't clearly see it the same way. This isn't a jab at you, everyone does this at some point in their life when something seems super obvious to you because you know something so well, but for others it isn't the same.
I hope after the jam ends you can update it to make things more clear, and then I would gladly give it another go :)
