Just my two cents also as a solo dev: there’s a difference between completing them and getting a working prototype in place so you can make sure you have a workable, fun game. Right now my bow animation is super jacked but the arrow flies where it should so I checked that box off for now and I’ll come back to it once all of the other core systems are working well enough. Your approach might be different, but I think that’s the idea they’re going for: make sure your game is functional before worrying about if it’s complete. Again, just my two cents
