This is 'Hero 30' (Half Minute Hero) released in 2009!
It was a game I really enjoyed on PSP when I was young, but I remembered it for a long time and brought it.
You must save the world in 30 seconds! is a game with a unique setting!
It was a humorous fantasy game, so it was easy to play and the story was interesting!
It's also on sale on Steam, so if you're interested, give it a try :D
