The game is beautiful! (/◕ヮ◕)/
I loved how some elements in the scenery looked like the critters and made my imagination go wild! The ambiance sounds where also really well put.
I feel like part of the game is exercising the volcabulary, but since the player doesn't know how do you named the elements, I would suggest that the "hint" mechanic could be seen by hovering the mouse in the objects. How do you feel about it?
