Yeah it's so annoying and no one ever did a proper tutorial unlike AA2 :/
Koikatsu is the spiritual successor to Artificial Academy 2, unlike honey select or play home it has a more anime look to it (you can turn off the cell shading though if you want to), its still happens in a academy but this time you can control your character with arrow keys, kind of like Artificial girl 3. The character making community started really quickly after the game released and there is already quite much unofficial content for it, seems like this one will stay on the top for a while. Also people was talking about some DLC stuff but im not following it for the passing months, they are taking their sweet time as always
