This was such a short and sweet game! Playing solo I got 4 of the endings, but I think i'll definitely have to grab a friend to beat hard mode lol. Overall really cute style and fun gameplay!
Thanks for playing! I'll post an endings summary devlog later today so you can see what Ending E is.
EDIT: I made the post here! https://3hg.itch.io/deadline-duo/devlog/643891/all-five-endings-a-guide
