THE BOSS BASH JAM

During this jam, you will have 20 days to create a magnificent, memorable and malicious boss, based around a certain theme. There are no prizes available, the jam is simply for fun and friendly competition.

RULES

MOST ASSETS MUST BE MADE IN JAM TIME - This rule will operate identically to last year. General use assets are fine, but you should try to make most of your game within jam time (at least 3/4, to put a number on it).

YOUR GAME MUST CONTAIN AT LEAST 1 BOSS FIGHT - The boss can be done in any format, you can have multiple bosses, and the boss doesn't have to be the only part of your game - but it should still remain as the main focus of it.

NO NSFW CONTENT - This jam is meant to be available to submit to and be judged by all creators willing to participate, therefore the games should be accessible to people of all ages.

AI CONTENT RESTRICTIONS - All use of AI generated art or music is strictly prohibited. You can use AI for idea generation if you wish. Please try to not use it for programming, there is a dedicated channel on the discord server for programming issues. 

THEME

Whilst the theme is non-compulsory, games which incorporate the theme will get more credit. Therefore, making an attempt to include the theme is always a good idea.

CURRENT THEME: AGAIN AND AGAIN

JUDGING

GAMES WILL BE JUDGED ON:

GAMEPLAY - Did you enjoy the game's mechanics/how it felt to play?

GRAPHICS - Did you like how the game looked?

AUDIO - Did you enjoy the SFX/music?

THEMING - How well did the game fit the theme?

OVERALL - How would you rate the game as an overall experience?
