That's fine! You have until 5 days after the jam to turn something in, even if it doesn't quite meet the 10 worlds, 3 effects, 3 events guidelines. Just don't give me Wakana Nikki and you're good. If you can't make it at all, that's fine too - when you finish, just send it to the Dream Diary Jam tumblr & I'll post it there for other players to see. :)
I hope your wrist feels better, that sounds terrible :c
