How to Play Zettai Zetsumei Dangerous Jiisan Tsuu: Ikari no Oshioki Blues
Quick start
Start the story of searching for the author's scattered manuscripts in ``From the Beginning'' and head towards the first department store. Investigate people and objects in the city, and pick up surrounding objects and throw them at enemies. The first boss, Nekozaemon, avoids his claws and picks up nearby objects to hit them. The transformations that increase when you clear a stage differ in the weight you can carry and your ability to move.
Controls
D-pad: Move/menu selection. A: Investigate, pick up/lift something (long press), throw. B: Cancel/transform menu. START: Pause/Status Menu. The reliable L/R function cannot be confirmed in the documentation and has been omitted.
