This is the walkthrough for Deluge: Threnody of Crashing Waves. To reach perfect scores for each character and unlock all endings, you should make decisions as described below.

1. I only had the purest of intentions.
2. Wouldn't mind visiting your church some day.
3. I'd be glad to . . .
4. Is there anything else you'd like to tell me?
5. It was just a wild idea of hers—
6. I believe he was called, eh— Spangler? (This option gives you an achievement.)
7. Will you please drop the charade?!

If your score is 3/7 or above, Rika will prompt you with an additional decision. (If you choose wrongly, the game will continue towards the decision point for Mei's ending.)

8. Sure, see you at eight.

During Rika's ending route, she will prompt you with one last decision. (If you choose wrongly she will prompt you once more, after which a bad ending is triggered.)

9. I trust you.

1. I'll keep my eyes wide open!
2. If you're sure no one will catch us. (Choose other option first to gain an achievement.)
3. It does look like an S.
4. I'd love to!
5. She's alright—
6. We'd better call the emergency services.
7. Let me take a look.

If your score is 3/7 or above, Mei will prompt you with an additional decision. (If you choose wrongly, you will continue towards the decision point for Ina's ending.)

8. I'm curious to find out.

During Mei's ending route, she will prompt you with one last decision. (If you choose wrongly she will prompt you once more, after which a bad ending is triggered.)

9. It is me.

1. I'll take it!
2. I thought I was just a paper boy.
3. She complimented you on your journalism.
4. Sounds pretty tame . . .
5. I'm afraid I have a lot of studying to do—
6. Looks pretty foolproof to me.
7. Sounded like a load of nonsense to me.

If your score is 3/7 or above, Ina will prompt you with an additional decision. (If you choose wrongly, a bad ending is triggered.)

8. I can’t agree with that.

During Ina's ending route, she will prompt you with one last decision. (If you choose wrongly she will prompt you once more, after which a bad ending is triggered.)

9. That's out of the question.

If you would like to play endings that you have failed to unlock, without replaying the entire first half of the game, you can rapidly skip forward by pressing down the [TAB] button.
