This was really neat! I loved the art and all the little stories. Unfortunately the cards would bug out a lot, which made reading the descriptions and stories rather frustrating (to the point where I couldn't complete the game).
Suggestions:
Perhaps make the ghosts halt their movement entirely when hovering over them, or have the player pick them up and hold them to read the cards. Or, perhaps you right click a ghost to toggle view of cards, and left click to pick them up.
(I tried both web gl and downloadable versions and had issues, and I did notice you mentioned the bugs in your page - so my rating does not take the bugs into account).
Overall, very cool game! If you can fix the bugs post jam, I'd love to give it another go and complete it as the story had me intrigued! :)
