The theme seems to be Strength In Numbers but could anyone tell me what does it mean or any simple ideas
The phrase "strength in numbers" refers to the idea that a group of people can achieve more collectively than they could individually. This is because, as a group, they can pool their resources, knowledge, skills, and effort to achieve a common goal. A group is always going to be stronger, more effective, and more powerful than a single person working alone.
The beauty of most game jams is the theme is up for interpretation.It could be a war game where the more units you have, the stronger you are. It could also be a little bit more general, the more of a resource that you have, the stronger you are.
Most games can fit into this theme: Call of Duty, Pikmin, Chess, etc.
The big focus is making sure that you also utilize the sanity system tutorial and implement that into your game, you need both in order to succeed.
Best of Luck!
