You've got really nice music. My main concern with the game is loading time. It takes too long for my device to respond to the event. The game stuck for tens of seconds, and at first I was so confused. It turns out it was loading the event.
And the description says that it's a point-and-click game. I was confused why I couldn't walk by clicking the floor, turns out the game is partially point-and-click. Using WASD to move the player
Regarding the art style, you can still polish the real world, making it finer and finer. The crayon drawing has its own uniqueness. But what about using the same art style for the whole thing?
