■ Chapter Mode
Various missions await you in each stage -- from simple to challenging ones. Clearing missions like “Defeat 30 enemies!” unlocks a boss stage. Defeat the boss to proceed to the next chapter.
■ Strengthen your craft
There are many level up options to strengthen your craft: shot power, shot speed, bomb duration, and more. Upgrade your craft and blast through the stages.
■ Great for beginners
Stages start off easy and gradually get more and more intense. You have no obligation to clear the difficult missions. If you get stuck, try your hand at another mission.
■ Simple controls
Use swipe gestures to move and attack, and tap with your other hand to launch bombs. These are the only skills available to you when you first start.
As you progress through the game, you will gradually unlock new abilities.
■ Easy mode
In Chapter Mode, you select the difficulty before starting a stage. Selecting Easy makes enemy attacks less intense and makes it easier to beat the stage. If you get stuck on a stage, try selecting Easy.
