Well, I got those cookies :)
At first I had a really hard time figuring out what I could walk on, and what I could not. I think the reason I had difficulty was because the dirt/ground tiles have boarders of snow, suggesting they higher/lower than the rest of the snow (I thought the white snow tiles were the ground at first). I would (maybe) remove the snow boarder on the dirt/ground tiles to give a better visual contrast, which may help make it a little more obvious at a glance where you can walk. To be fair, once I figured it out I had no difficulties, so maybe no changes are needed.
The only other thing I had difficulty with was I did not realize I had to go through the burnt house to get to the lake, though that is my fault since I missed the clue in the text the first time.
Other than that I was able to successfully go through the entire game, and it was pretty fun! I really liked the RPG Maker vibe I got, especially from the text boxes.
