An easy method to collect the voices (dialogues).

Detail

Enter a puzzle, find a piece of block that is at the correct location.

Switch this block with another block on the screen, then switch them back. You will get one sentence.

Switch the correct block with a different block as the previous one, then switch them back again. You will get another sentence (but can be the same).

Repeat the process till you have switched that correct block with every other blocks on the screen. Then you will get no more sentence. Now finish the puzzle.

Do this on every puzzle of a certain level, you should get all the voices (dialogues) of the level. If not, replay one of the puzzles.

Example

My description above might be confusing. Here is an example:

For O is a block that is known to be at its correct place. and A B C D are just random blocks as X
ABCDXX
XXXXXX
XXXOXX
XXXXXX
XXXXXX


First switch between A and O
OBCDXX
XXXXXX
XXXAXX
XXXXXX
XXXXXX

Then switch back. You will get a sentence (You may need to wait for it to finish itself, otherwise I don't know whether it will be collected).
ABCDXX
XXXXXX
XXXOXX
XXXXXX
XXXXXX

Now switch B and O
AOCDXX
XXXXXX
XXXBXX
XXXXXX
XXXXXX

Switch back again. Now you will get another sentence, which could be the same or different as the one before.
ABCDXX
XXXXXX
XXXOXX
XXXXXX
XXXXXX

Then switch between C and O, switch back; switch D and O, switch back...and so on. As you go through all the blocks, You will get all the sentences you can obtain in this puzzle play, now you can complete the puzzle.

Hey I've got a question for the Main 3 girls' (Renki, Iris and Michelle) Glass_Epilogue voicelines, I've played all stages from level 1 to 5 without ever skipping dialogue several times but I just cant get the Glass_epliogue after the Girls' specific epilogue. Am I doing something wrong?

[QuBee]

Thank you so much for this. Without your guide I wouldn't have known how to get to 100%.

Tip: Everytime you move a piece and hear a sound (let's say an okay sound), is when you unlock a dialogue. So move each piece around to every single block to unlock new dialogues. The sound that makes is like when you place the piece in the correct place.

I've never cheated on the game (I didn't we can cheat on the game xd). I completed the bonuses but I can't get the voices. And the bonus scenes don't appear in the game like the dlc levels. Is that a bug?

[Helium]

According to a developer, the epilogue requires to finish 5-3 without cheating (skipping?), then there will be a bonus stage 5-4, which will lead to the epilogue after being finished (still without cheating?).

How can I unlock the GLASS_Epilogue voices?

[RowdyOne]

Thanks for this, it's helping me a LOT. I can't seem to figure out how to get the "GLASS_Epilogue" voices for the DLC characters though, are you able to help with that?

It was so useful that I collected full voice achievements
