I liked the puzzles and how you have to change your character to do different things. Maybe it could've used a bit more story but I understand time was short. Nice entry!
Yes, you have to follow the arrows to the forest (after you've been to the apple house) and then go up into the three different areas with puzzles. I would suggest you don't exit the forest, just keep going right otherwise you might get locked out.
Ah, thanks! I didn't notice any exits and thought the game was unfinished. The puzzle stages were quite fun. More puzzle game than adventure, perhaps, but entertaining.
