This is such a beautiful game...
I like how understandable and grounded in reality it is. Ecosystems work similarly to how they are depicted here, and the mechanics work very well with that depiction. All the resources are unique and rely on each other to grow, creating a sense of satisfaction and ease of play to the player. It's fun to watch something that you created flourish, and to learn about how nature builds the world in the process.
The pixel art style is very fitting and cute; I would imagine the game to look a bit boring without them. It's so cool how you can depict animals in the tiles that can house them, all with like ten moving pixels lol. It clearly communicates what's going on and the impact your ecosystem is having on the wildlife. That impact is very rewarding and satisfying to experience!
Everything about the game comes together to create something truly beautiful. Excellent work, and please keep it up!
