Action Quest Available

You need to upgrade and purchase a weapon, equip it, and then clear stages. The game itself is average; it's neither particularly fun nor boring. However, there are quite a few ads, and weapon upgrades are essential. The deadline is to clear Chapter 25 within 9 days. Reviews suggest it's not a very difficult quest, and from what I've played briefly, it's not overly challenging. It's a simple game to play.
