I have learned that I am stronger than I thought, to finish at least one game :)
My new principles:
- Keep it simple - Before adding new details try to play around with less.
- Gameplay first - I struggle with it every time. Try to create a good mechanics and balance it before bringing all other stuff like effects, art, e.t.c. I am kinda visual persion, so it requires imagination.
- Focus on the goal - If you made decition to implement a thing, and you sure it will make your game better, then just do it. It was really difficult for me to decline all new risky ideas that I had no time for.
