Good advice! I'm a bit tired now, but I wanted to make sure I at least finished the basic system and the prologue—something I promised more than a year ago. From now on, I can relax and add things in smaller updates whenever I want, knowing that I won't break the game.
Not yet. As of now, the tutorial fights are heavily scripted so that it's impossible to lose. (I hope!) But now that I've finished the more pressing tasks, I can start adding more scenes or variations of existing ones.
I just need to decide where and in what style to write them.
