This is just the preview.
This is Top Secret It's not actually a sim game but more towards visual graphic sort with a bit of dating sim.
It's about agent, spies, secret mission, explosions, project and stuffs. There will be some mini games on how well you can complete the missions.
You can play as either Natsumi the cold sniper or Sapphire the cunning spy. You'll have rivals along the way and the rivals/ enemies will try to stop you from completing your missions.
I've already done the opening MV and ending MV for Top Secret but there's something wrong with the opening so I have to re-do before I can submit T___T
The song is Speed Star from Namie Amuro
