Progress on this project is coming along really slow. I have to admit that it takes some time to get into a whole different language (Haxe) with my second project with HaxePunk. This, in combination with other time restrictions (work), makes me doubt if I can finish this game within May. I really hope to implement the basic mechanics to try it out.
Nevertheless, here is a screenshot of the extended tree generator. I only have too add some leaf (circles) and then I can get to the game logic and interaction.
