I just joined the GMTK this weekend and published my game to my account. Leave many things unfinished and feel great in this experience. While still have many points need to work. For example, I found my codes is not very clean and many traps, I made one single script to achieve. And the singleton pattern I used in my daily life appears some "null if instance" during different scene. Anyway, I will keep doing and makes program easy to read and clean. Also make the game more attractive.
