Dream Diary Jam 10!
10 years of making dreams come true! A decade of discovering dreams!
Jam runs from May 15th, 2026 to June 26th, 2026. Much like previous jams, you can join before or during those dates!
Welcome newcomers and veterans to Dream Diary Jam 10, a game jam all about the creation of fangames for the cult classic RPG Maker 2003 game Yume Nikki. The goal is to create a Yume Nikki fangame, a demo of one, or to even update one of your previous entries. You’ll be given 6 weeks to work on your fangame, starting on May 15th and ending on the June 26th — Yume Nikki’s 19th anniversary.
Submission types:
Traditional Yume Nikki Fangame - The most common type of fangame. Typically follows the same formula/style as the original Yume Nikki, but with an original cast of characters and environments, and sometimes new mechanics. You can get as experimental as you want!
Examples of this type include: .flow, Yume 2kki
A Fangame of the Yume Nikki setting - A fangame that uses the characters/settings of the original Yume Nikki, rather than a new original cast. Think something along the lines of fanfiction. This can be any kind of genre, JRPG, dating sim, clicker, etc. You can even make a fangame of YUME NIKKI -DREAM DIARY- if you want to.
Examples of this type include: NASU Plus, Memories of Replica, Dream Kombat, and Yume Nikki Hazard
An update to a previous submission - Didn’t get to make as much as you wanted in a previous jam? Need an excuse to work on your fangame? Don’t want to start anew? This is for you! If you can provide a substantial update to one of your previous entries, then it’s also an acceptable submission, even if you’ve been chipping away at it outside of the jams.
