The theme of the #MadeWithDefold Jam 2024 is "ONE TOO MANY"!
It can be interpreted as "Ooops, one too many!", one additional feature that affects the game, something overflown, overpowered, exaggereted. Players might face situations where having "one too many" of something leads to unexpected consequences, e.g. taking "one too many" items might slow/affect/change the character. The player might be tasked with balancing items, elements or forces, and adding one too many could disrupt the balance. The narrative could involve a protagonist who indulges in one too many of something. "One too many" could refer to an overpopulated world where resources are e.g. scarce, could explore themes of consumerism and excess. I believe there are many, many possible ideas and probably even... one too many! ^^
We're counting on your imagination! ;)
P.S. The image below is from what the idea was born! :D
