Addition of multi-agent environments

[parthkhopkar]

Hello! Thank you for making this extremely useful extension to minigrid. Do you plan to add more environments from literature (e.g. predator-prey) and make this repository as robust as gym-minigrid? If so will you have contribution guidelines in the future for pull requests?

Same question here. Thanks for your amazing multi-agent minigrid. It seems that here is no key and door in the environments you implemented. Do you plan to add them? \
