This game is Bullet-Hell(STG).

The beginning of the second game story...

The lead character who calmed the first turmoil in a dream...
Yeonseul returned to his shrine in Hyeonmongdowon and knocked down the gloomy body.
“Is it the first time… I’m getting heavy.”
Then the,
'What should I do in the future?''Who will I meet?''Is there anyone else who cares for me that I don't know?'...
In this moment, various worries have come,
“shall I rest next to the cool water…”
Soon after lying down, he got up again and arrived at a river near the shrine to climb a rock.
The calm darkness of the dawn and the cool feeling and clear sound of the water seemed to comfort the chain more.
While absently resting on a rock, he encounters another sign of commotion.
“Have there been fireflies like that…? It’s cooler, so it’s more interesting.”
"Oh... the size... has it changed? Something strange...”
So Yeonseul doesn't rest properly and goes out again to find the source of the sign.

How to play the game
1. Normal mode (game start menu)
Whenever you enter each chapter, avoid and attack multiple enemy attacks that will appear for a certain amount of time and shoot down!
After a certain amount of time, the boss comes out and dialogue to the player and starts a duel with the player.
Beat the boss and enter the next chapter or look at the endings!

2. Boss rush mode (BR Start !! menu)
Normal mode is difficult to continue (within a limited number of times) regardless of the number of times to unlock the mode. (clear once)
