I always find planning out each episode helps like I have notes on my phone like this
Story title
scene 1-
Scene 2-
Scene 3-
Scene 4-
Scene 5-
then I write what happens in each scene and what choices happen so its planned out so I dont get writers block but also gives me freedom to change things
I’ve done this for the first 3 episodes
I also got stuck on the 3rd episode. I think for me is that I got too excited and I want to rush things. Still take things steady, keep looking back at the last episode to see what you can add to this episode. I also planned/thought out scenes I made up on notes on my phone. That really helps cut down time.
