Of course, you can! Don't worry about it!
You can first finish the next update so that you won't have to worry about not planning thoroughly on what to do next.
When creating something, it requires not only time but also effort put into it from start to finish. It may seem hard at the beginning but, don't get discouraged by that. There's plenty of people that will ( and probably some already did, myself included) recognize the effort you put into this game. Stay awesome!
