Ok so I had this idea, for an open world exploration game in space. and basically you're in this universe referred to as "The Pandora" its basically just an alternate universe. So inside the pandora it goes like this.

[Universe > Vector > Galaxy > Star system > Planet] So your character a little space man which I haven't designed but I have an idea in my head has a grappler to go from planet to planet. now I know its a key factor but I have not decided on 2d or 3d yet. his grappler has a red button and upon being pressed it turns into a weapon, so you may fight enemies. Now this is just the initial idea I have not started working on it yet but im looking for; Coders,Artists,Music etc there will be a link to the discord down below if you are interested. and here is some first look stuff at the project.
