so in order to unlock free mode and be able to get all scenes, what do I need to do? and are the patch needed?
You need to avoid all the bad ends. The guide has info on how to do this.
I'm not sure if the patch is needed, as I got my version of the game from the dev's website.
Can someone help in how to unlock the construction site? I read the
WALKTHROUGH and its not helping. Its says i need to talk to some slacking guy in front of the school but there is no one not on week days and not week ends.
First, you need to start the recipe "Ayame giving a handjob at the construction site". Then go to the construction site, then the school.
There are 6 things you need to get to unlock the zoo.
Chewing gum - buy from the convenience store.
Address to a great restaurant - Talk to Atsushi after starting the quest to unlock the zoo.
Four-leaf clover - After starting the quest, go to the playground on a weekday. Click on the shiny spot.
Picture of happiness - buy 8 bottles of beer and talk to the guy at the construction site in the top right.
Expensive sake bottle - go to the dump an talk to all of the guys there, then go find the last homeless guy at the shrine.
Collector card of Kiki - After Yuki gives 2 handjobs at the construction site, talk to the guy you have the handjobs to. Then go talk to the librarian. The next weekday, go back to the library and talk to the old man by the window. To get the card for free, select "For someone we don't know" > "It's to help a friend of ours" > "We're helping a porn actress buying a zoo". Or you can also get it for free by choosing "Form someone we don't know" > "That's what they want for being bribed" > "Our lives are at stake!".
