In Zero Castle , you take control of a rotating flying castle, each with its own unique characteristics. Your goal is to destroy enemy forces and fight your way through the game.
As you progress, you'll collect money from defeated enemies, which you can use to upgrade your castle and unlock new systems. These upgrades can give you an advantage against the enemies that await you.
The upgrades you choose will shape your playstyle. Choose wisely and build your castle to suit the way you want to play.
But staying alive is no easy task. Your goal is to complete every level and all of its cycles without running out of lives . With each cycle, enemies don't just become stronger — new and more challenging enemies will also join the fight.
If your lives reach zero, it's back to the beginning.
You can purchase an additional life to keep your run going, but it comes at a very high price.
Choose your upgrades. Build your playstyle. Survive every cycle.
