Welcome to MillieJam!

we return better than ever.

This is a game jam heavily focused on community and having fun!

Feel free to make a new game, enter this concurrently with another jam, or use this as an excuse to polish up one of your previous games! We're all in this for fun, to foster a nice corner of game devs, and get Millie in as many places as possible >:)

all updates are in the discord: discord.gg/WhhKrUdGFJ

(we are really cool and swag and we have a bot that sends Millie pics on demand)

---

barely any rules -- just no ai art, let people know if your game is NSFW, and be nice!

you can work on any game, at any time. there are categories for judging, but the most important rule is to HAVE A GOOD TIME!

The optional theme is HALF AND HALF.

a list of ideas has been sent to the discord if you need help brainstorming!

Following this theme won't get you any extra points, it's meant only for help with brainstorming if you need! obviously the real theme is millie ;)

Prize Given to
$30 from my broke wallet 1st place
$102nd place
$12 because Millie is 12! raffled off! If we get 12 entries I'll just give $1 to everyone LOL
secret :3c secret >:0 (may or may not happen, but if it does there are no limits. i could buy you pizza or some game or fund your steam game)
*up to $50, likely given to the best games that i enjoyed on stream

if you show proof that some important event (your bday, an anniversary, etc) is during milliejam i will give you something as well!
Millie sticker!? whoever can reasonably reach the bay area (california) or boston*

*Might ship some as well for people who really really really want one (it'll take a while to make tho so also dependent on time)

JUDGING CATEGORIES

Judging will be done by community members! Please leave helpful comments. BE KIND and don't review bomb please* :)

Category Explanation
silliness we tryna be silly around here! the game doesn't have to be "funny" or tryhard, just how much you enjoyed playing it :) (how good were the vibes?)
millieness how much millie? how good was the millie appearance? did it make you laugh/smile/react? do you admire the effort
goodness what a fire gameself-explanatory 🙂‍↕️ kudos kudos
(previously named "genuinely a good game")
creator's community impact is the creator cool? did you interact w/ them? how funny is the creator on a scale of 1 to 5. it's time to judge (jk this is just to motivate people to interact more :))

*I may randomly pick a category at the end of the jam to determine the winner so that it hopefully discourages review bombing (PLEASE do not review bomb). If there is review bombing (average <3 stars in most/all categories or people just think it was present) I will just give the 1st place prize to whoever had the most messages in the server during the time period.

a: the host's cat <3 we have a bot in MelonJam that sends millie pics and since then she's been our icon

q: theme?

a: there will be an optional theme released a bit before the start of the jam!
