Hidden achivements
Unlocks when you face Mechachu for the first time.
Happens on the final act and the first battle is always set to lose regardless of your choices.
To get this one you have to game over on Act 2. Play Act 1 normally then go for all the “wrong” anwsers on Act 2.
For this achievement, you have to game over (by filling up the heartbreak bar) on the first act. This bar goes up everytime you fail a date.
To fail a date you have to pick all the bad options, especially on the last question of each date, which determines how the date went.
This achievement is tricky to get because the game will try everything to make you progress to the next act.
You do not have much room for errors and you might also have to restart all over again depending on the questions you get.
Make sure to SAVE your game after every “unsuccessful” date! so that in case of a mistake, you can always reload the file and try again.
In my attempt, I picked Garudan, the fitness loving fowl but you can try with other Kaiju.

After date 1, the questions will be in a random order. From here on, you cannot get any good nor great date endings because that will make you advance to act 2.
Sometimes you might get too many all good/great response questions during a date, forcing you into a good ending.
