Update! Sorry for minimal posting but I've been making some changes in the background. Namely, I'm scrapping a decent portion of the specific things I've designed like plants and characters. There are a few reasons for this.
I felt that the system for environments was too ambitious. I want to simplify the world generation and the plants/creatures that live within it, so I'm redesigning a lot of them to be more cartoony in both appearance and actions.
I also decided to make this game more unique by tying it into a story series I've already been writing. Instead of everything being based on existing things, there will be a mixture of recognizable flora and fauna, plus many alien lifeforms. That way, I'll be less restricted by the accuracy of real-world details and the world will be unlike anything in any other game (kind of)!
Please let me know if there are specific things you'd like to know more about such as concept art, mechanic plans, technical details, etc. I'll gladly share! I'd dump all of it, but trust me, its too much for one post.
