I have a pretty exhaustive list for how I would fully build this out. But, I learned so much making this that my next release will be my own IP so I can try and sell. I do want to do updates for this over time though.
Yeah took me a year. Still trust me bro, it's worth it. the community is just not the same as Youtube. It's so much more unhinged. And Mecha games tend to be hard to find here. Good luck man.
