Welcome to MelonJam 4!

Jam winners have been announced in the Discord server and a community post! For feedback and rankings, please visit this sheet.



The theme for MelonJam 4 is CORRUPTION!! A loaded word with tons of definitions (scroll down to see some), you are free to interpret this theme to make games ranging from one that slowly “corrupts”/breaks (e.x. There Is No Game) or a visual novel highlighting corruption in society to an idle game about being a corrupt politician who loves stealing money from the poor.

A few notes before you start:

- “Corruption” should be present in your game, but you can choose how you’d like to present it. Keep in mind that you’ll have to explain in a few short sentences how your game relates to the theme, and that your submission will be graded on how innovative its interpretation of the theme is.

- You are required to keep a document tracking all the assets you used that were not made by a member of your team during the jam.

- Please do keep in mind to not actually submit a corrupted file or expect cybersecurity knowledge from anyone – we’d like to protect our judges and other participants to the best of our ability, so please upload a web-playable version or your game may not be judged (contact hosts if this is an issue).

Need more prompting? Here are a few definitions of corruption:

1. The act of changing, or of being changed, for the worse; departure from what is pure, simple, or correct

2. the process of purposely breaking a game

3. dishonest or fraudulent conduct by those in power, typically involving bribery.

4. the process by which something, typically a word or expression, is changed from its original use or meaning to one that is regarded as erroneous or debased.

In this game jam, we are inviting both beginners who have little to no major game development experience and more advanced developers.  The theme announcement will mark the start of the game jam, July 21st 12:00 AM UTC, and the game jam will end on July 23rd 11:59 PM UTC for a total of 72 hours.

We recommend visiting our website for a recommended schedule and more information!

We will also be posting most of our updates on our Discord server, so join here: discord.gg/uYmNuZymJ2
