Hey, a fellow dev here! I can relate to these pains - I only got my first game out but it's after months of (re)doing things over and over again.
It's wise that you narrowed the scope - it is better to iterate than to hold until everything is perfect. Which piece of art is perfect? "the work is never completed, only abandoned".
What do you use for animation - sequence of still images or rigs?
When do you plan on releasing a playable version?
Good luck!
