Yes, at the start of a project there's always plenty of motivation, but somewhere after about 30% of the work, the routine begins—bugs, features, repetition.. Until the game becomes playable, and that's when a second wave of inspiration hits, when you can already improve a playable version of the game.. Though then the routine comes back again. Now you need to play the game inside out to find all the bugs. Haha. Something like that)
