I think this is a great idea that just needs more development to be fully realized. The art style is endearing, the fantastical take is a fun one. I think the tie to the theme would be cooler if we received more information about all the natural elements (like the Dragon's Blood tree) while playing. Maybe a mechanic can be added so that in every level, or wherever the player reaches in the world they recieve a new organism or environment to protect alongside an introductory informational placard for immersion. This reminds me a lot of fantasy open world action RPGs like Genshin Impact, which is something maybe can be sonically and mechanically taken inspiration from. Good luck!
