I was like awww such a cute little game, until I hit R :D The atmosphere is great, I really like the ambience. The leaves falling, grass rustling. It gives you a cozy feeling. Probably I am not the first one to tell you, it is a little bit hard. My main difficulty was hitting the little imp thing that comes super fast. BUT it is good that you gave it a flying sound, so I could at least aticipate it. A very intersting entry and much more than what meets the eye on the first glance.
p.s.: your game reminds me that I should really start to learn shaders. They add so much to the game.
