You mentiond an interesting point there with the larger maps. When we were design the game we also thought of using a larger map. The problem with a larger map is, that when make it even a bit larger, we multible the change every time the screen gets split again. This would mean, that everything on the screen would become smaller and isn't as easy to recognize. However if we didn't let the world split that many times, we could probably make the map larger. We are thinking in the moment of ways for the player to have a better sense of what is going on, so maybe we will do that.
Thanks for you feedback. I am glad you enjoyed it :D
