Any suggestions are welcome for a new upcoming project

Hello everyone. I recently had the idea to realize a 2D game where you are an astronaut in an enviroment where there is no gravity and the character physics are well simulated. It’s highly inspired on the game “Heavenly Bodies” (Heavenly Bodies - Gameplay Trailer | PS5, PS4 - YouTube). The are a lot of things to take care of, such as the arms physic simulation of the character, or the locked body orientation made like HB. Of course i would like to make it multiplayer and give different tasks and meanings to the game. What do you think? I would like to talk about the making of it as the it doesn’t seems to be easy.
