I was just informing you incase of someone else, I've hear the same complaints when I create games, I am not trying to concern you or make you stressed, I am only trying to help. Keep your work up.
Oh! Sorry, I misunderstood.
The main reason this happens in indie development is to avoid burnout or poor project management in scope. Sometimes you design something much bigger to pull off than you realize and rather than scrap everything you've made thus far you make something else as a break.
The other side of this is near the end of development, and it'll happen with Password as well, you'll typically want to start development on something else so you have something being worked on by the time the first project ends. Mainly so you can keep getting an income, but also it's just good practice to have something prepared for when your project is over if you're wanting to continue working as a developer. But again, normally you'd wanna do it near the end of development and not in the middle.
