Hey,
First of all the Graphics of your Game look so Appealing and Cute!!....Great work on that, and Awesome Presentation
About the Node Map, since your Game is Oriented in a Landscape View, it'd be better to have the Node Map in a Horizontal Orientation as well as it scrolls towards the most accessible direction....If your game was in portrait mode the vertical would have worked better....But this depends on the preference and Visual Direction you'd like to go in the end....
Anyways, great work, and hope to see more awesome content for Posey Picks👍
