The environments are often really beautiful. The game looks so appealing in fact, that I wish I could actually jump into the background and explore the world. Vast jungles, wide open fields, little towns with windmills, mountains, the sea floor.
What do you think? Are you fine with it being 2D? Does it bother you slightly that you can't explore the background?
A follow up question, would you be annoyed if Retro's next game was a 3D Donkey Kong game instead of Metroid? Do you think it will happen? I could see it happening, given how much effort they've put into rendering 3D models into the background already, and the fur physics. But my guess is that it's unlikely.
Btw, I'm not knocking the game. It's an absolute must have.
