What I want is a multiple scenario game, and each scenario will consists of a few people, and a few artifacts such as ropes, planks. For each scenario, there will be a situation or a puzzle, and then user needs to solve that puzzle using the existing artifacts. This means you need to,
1. Create a scenario such as an open ground with some puzzle task. The scenarios will be simple to create.
2. Apply physics to people, ropes and Planks.
3. User should use Keyboard keys/Other inputs to solve the puzzle.
Example of such scenario - One person (user) is responsible to help other people (computer) to cross the river using few planks.
