How to beat the hidden stages~~

Gunslinger Cat is an idle RPG where cute cats wield guns and automatically attack enemies. In the early stages, it's best to prioritize attack power and gun upgrades over saving acquired resources to push through stages as much as possible. Especially since you can combine the same guns to create higher-grade weapons, instead of holding onto low-grade equipment for too long, consistently synthesize them to boost your firepower. It's also important to collect and grow various types of cats to increase your overall combat power. If you're stuck on a stage, rather than just waiting, check your gun synthesis and character upgrades first. If you're still having trouble progressing, it's recommended to utilize reincarnation. Reincarnation resets your current progress but provides a stronger foundation for growth, allowing you to break through the next sections faster with each repetition. Also, since offline rewards accumulate even when you don't keep the game running, it's good practice to collect your rewards first and then upgrade when you log in.
