This is not a walk-through this is an achievement guide.
This game leaves no room for achievement guide, without spoilers.
Sorry if this offends anyone looking for just a guide, this isnt that!
Achievement guide below!

To complete Erica 100% you need to play five times.
One play-through takes at least an hour and a half. (or less)
All achievements are given at the end of each play.
There are collective achievements in the game, that add up for the next play so you won't be able to get them in one play. Enjoy!

I have edited Play 1-3 For better translation. Feedback is gladly welcome

Please note: tallied achievements ARE broken. Somewhat fixed!

If you have these achievements in steam you didn't get them the proper way.

This is a WIP I shall be adding achievement icons/pictures next to the area where you should obtain them. As well as re-wording for a smoother English translation.
I just wanted everyone not to have to go to google translate and or hurt their heads.
If anyone would like to help me with the images for the achievements let me know
I dont have them unlocked at this point as I just got the game.
Hugs to all and I hope more FMV games come out, as they were awesome in my childhood coming from Sierra and other places.
