I second this.
@Cody17, typically a theme for a game jam cam be interpreted in all kinds of ways. Part of the spirit of the game jam is coming up with creative ideas to set your game completely apart from the others and a big part of that is interpreting the theme in a way no one else did.
For instance, a game jam I was in had a theme of “loops.” One group made a game about the solar system (an orbit is a type of loop), one made a game about having to replay the same battle over and over again (temporal loop), and my game was about wrangling cattle with a lasso (a rope that is looped).
We want people to come up with a game based on the theme, right? We don’t want the theme so hard that people make a game and then just slap the theme on afterwards as an after thought. That is what may happen if you corner their creativity. Just my two cents.
Anyway, I have a fun theme that doesn’t seem too difficult to pull off. Might take a lot of sprite work, though…
