i miss you bro
If you love Wario and absolutely extreme amounts of detail, this book is worth a shot! It contains an analysis of every enemy, object and room in the game, in 583 pages.
Hmmm. Wario Land 4 is a really good game, aside from its length (or lack thereof). So was its sequel, which took a similar formula and improved on literally everything while adding beautiful hand-drawn animation in the process. I was just thinking yesterday how we are long overdue for a new installment.
