The game world felt lush and alive. The forest background, the swaying grass, the woodpeckers, the birdsong, the running brooks... I really appreciate the attention to detail. Similarly, it was great how there was a full front end, including credits and tutorial.
Unfortunately, the win and lose conditions are not explained. I couldn't figure out how to tell the good mushrooms from the bad. As thoorin notes below, this should have been covered in the tutorial. Alternatively, it should have been clear from the head up display. As it is, the only feedback I got was when the game was over, but I didn't know which mushrooms were which. Plus, how many good mushrooms do I need to win?
Also, I was having difficulty jumping up ledges. Even though I know the character can jump high enough, he kept getting stuck on the sides. You might want to try a frictionless material on the player.
