Have you heard that ConcernedApe took a break from working on their new game to do one last big update for Stardew? Things like improvements for mod support, some more storyline dialogue, a new yearly festival/event, hats on cats/dogs!, seasonal clothing changes for NPCs, I think additional Joja content, and something else for Ginger Island. No release date confirmed yet, but CA can take as long as necessary to work on it, I’ll still be patiently and excitedly waiting!
Some cutesy games that I found.
GBA:
MegaDrive:
SNES:
The Great Circus Mystery game was one of my favorites to play with my younger brother. It has an amazing 2 player mode where a second player can join at any time, which probably doesn’t help in this case, but it’s a great game to play together. Similar mechanics and style: The Magical Quest Starring Mickey Mouse. These 2 games (and the third game) are also on the GBA and listed above as Disney’s Magical Quest 1, 2, and 3.
I’ve only personally played Ariel the Little Mermaid and Great Circus Mystery, all of the others I just now opened to get an idea of how they play to see if they’re cute. If many of these don’t fit the bill, I at least highly recommend the Magical Quest ones on either system. I hope this helps your search.
