I Became the Tyrant of a Defence Game

Tyrant of the Tower Defense Game,디펜스 게임의 폭군이 되었다, I Became the Tyrant of a Defence Game

The tower defense & dungeon offense RPG,
I watched the ending of the game on a difficulty that no one has cleared yet.
But when I woke up, I was inside the game. On top of that, in a tutorial stage that I can’t seem to beat.
“I’ll clear this damned game at all costs…!”
