Interesting game idea! I couldn't figure out how to get an eco system going, maybe a smaller sample of how to use plants and tools to create the required nutrients for other plants would be helpful. I would suggest taking this further as a mobile game, it's a neat concept
great idea, and well put together! I had a bug where once I snapped a picture of a stingray it wouldn't log any more creatures afterwards, it always assumed each new picture was still a stingray
