Most of my insights are similar to others, so I won’t repeat in detail here (pacing is important, keep it fun, etc.).
On a personal note, my Japanese is not that good (could probably pass n4 but would definitely fail n3). In the past, I got so frustrated with kanji being my weak spot, that I guess doing the entire WK course felt like something I could do to OVERcompensate, if only so I could back off the kanji learning for a while (hopefully several years!). Of course, I’ll try to brush up now and then to avoid unlearning…
One question I’m dying to know … if I close the “レベルアップおめでとう！” window, will I ever see these cute little durtles again? Does something else appear in the blank space, that I’m currently missing! Help!
