I have to be honest but I would like to start with the positives. I am a sucker for cool art and wow the art style of this game is so damn beautiful. I love it to death!
Additionally, the concept sounds awesome! I can't wait to see this game become what you want it to be, and I will be the first in line to play it when it does.
However, I have to add a few criticisms as other's have mentioned, there are quite a few bugs as other's have mentioned, which is completely expected for a game jam and as such I really don't hold it against you.
Funnily enough, the main issue for me has to do with the thing I love most about it! It's so damn beautiful that my computer has a stroke trying to play it! The addition of graphics settings would really help so many more try your game and fall in love with it's art like I have.
All in all though I really like the game and the idea! Be proud of what you've made so far, even if it isn't perfect or what you necessarily want it to be yet.
Great job friend! :D
