Definitely. You've got a really solid foundation there.
If you're open to suggestions, I'd recommend a slightly more tactical way to build your deck. Only light, to keep with the slower pace of the game, but just something where you have a little control over which 'treat outcomes' (i.e. bat, spider, vampire etc) you will create, then the player is making a more involved decision of "I'm picking these specific treats for this specific character".
Or you could keep the deck itself random, but make the choices a little more tactical, like by skewing the deck in favor of a certain emotion, so the player can say "this'll be best for a sad character", or having slightly more limitation, like you can only use 3 cards per deck, so the player doesn't blindly shove every card on one character!
Just a couple of ideas- feel free to use or ignore!!

Thank you yes I'm very open to ideas. One of my problems picking this genre is that I have never actually played any of these card games before - I just thought it would look cool! Now that the jam is over and I can take my time with the game I think I want to spend some time playing more card games and seeing how the mechanic works.
I definitely want there to be some element of strategy, even if it's fairly light. I didn't really want it to be just a click fest through the resident stories and then the game is over which is what it would be if I just kind of finished what I had now.
I haven't played many card games either. Sometimes it does help to play lots of games in a particular genre, mainly to get a feel for how they're built and balanced, and the mechanics they use. However, it sometimes helps not to delve too much, because it generally makes your own concept more unique. In your case, you've already grabbed yourself a pretty unique concept by working 'blind', now you can get some inspiration from elsewhere to build on it :)
Best of luck with it!
