O2A2 Visual Novel Jam

The O2A2 VN Jam stands for "Only One of Any Asset", and is a week-long minimalist visual novel jam with restrictions on allowed assets, while keeping the themes free. The goal is to create short and self-contained works.

History

The jam started in May 2020 as a way for mikey to create a fun and simple week-long challenge for another DevTalk community user to pass the time waiting for another major jam. To aid motivation, mikey promised to join as well, if the challenge was accepted. After a simple jam page was created, the invitation was extended to anyone else, with only a week's notice before the jam began. The jam ended with 20 finished works, and was a surprise success.

Initially mikey had no plans to run the jam again in 2021, but later on by popular demand together with BaiYu who created the 2020 logo another round of the jam was set up. This time the jam was promoted more intensely and produced almost 5x as many entries. Due to the ongoing OtomeJam, the jam was scheduled for July.

In 2022 the jam was set up again, with BaiYu as the leading host, together with PRINCESSINTERNETCAFé, in a similar July time slot.

Rules

The following rules are taken from the O2A2 2021 itch.io jam page:

It's simple, you have one week to make a visual novel and you can use at most:

• one sprite / one character / one pose (multiple expressions without change in pose are okay)
• one background / one place / one time of day
• one illustration (in place of the one sprite and one background)
• one thousand words
• one music track or one ambient background noise
• one sound effect
• one voice actor
• one piece of menu background art
• one project (submit only one entry where you are the creative lead/director. You may participate in other teams as a different role)

Further rules specify non-restricted areas, as well as disallowed content.

Trophies

To encourage the spirit of the jam, at various times trophies were given out to participants. These are called "Obfuscated Achievements", and all of them have some form of words starting with "A", and "O". In the first 3 jams they were not revealed to the participants beforehand, and were "unlocked" only after the first VN that qualified for them was released, or revealed at the end of the jam in full. Over years O2A2 trophies may change names while their substance remains the same, or a trophy's criteria may change while its name remains.
