About Koikatu!
Koikatu! (コイカツ! or Koikatsu!) is 2D Cellshaded character creator eroge by Illusion. You play as a lonely boy who just got transferred to an all-girls-only school with the purpose of.. getting them accustomed to the other male classmates. Roam around the map, peep on girls if you have the opportunity, talk to them to gain their favour and trigger “events” that will unfold their stories. There are “named” heroines with a preset backstory and player-created characters with plenty (30) of personality types to choose from.

For me says the first download link is corrupted. I tried to redownload it again three more times to no avail. Is there an alternate download link because I would really like to have this game.
for everyone with the crash on start problem: just wait 2 minutes and the game will run
How do I run the game properly? I run the game through just the applications and through the initsettings launcher and it just brings up the is not responding screen
May just be missing some program but I’m a bit confused. I downloaded the 6 parts, unpacked and now I have 6 files with about 20-21 gbs of data but there is no launcher. Does it need to be unpacked beyond the windrar file, and what program is needed for that?
Select all the file and click on right mouse button then select extract.
And we recommend 7zip
How do you save the game
It has to go in Userdata/Save/Game
How do you save when playing the storyline
Game never starts, just a black screen, and CharaStudio loads infinitely.
This game seems to have lot of bug. hope the devs will fix em in upcoming updates.
The game itself is finished, only mods are available. This particular version is bugged heavily because of the choice mods added to the game. You can use Kmanager to enable and disable mods efficiently. With the amount of things already edited here though, I would just download or relink to a vanilla version with the sideloader option.
AIO download is broken – file wont open
Try the latest version and check if the problem persists.
needs a password
No need for any pass.
I installed the 9 parts but I can’t extract them and even if on files it is written the stored in when I enter the files they are empty.
Please try extracting with 7zip.
How do I play the game if I have downloaded it in separate parts?
After downloading all parts, select all and extract altogether.
