This bug is still here, exclamation mark in beach and can't progress the "give marry a massage" to next level. Can't progress the story.
I looked into this and there's indeed a bug preventing progress from a certain point on, caused accidentally when updating the massage scene.
If you are playing the PC version, please use the following patch to fix it. It'll be added to the following update.
If you are *not* playing the PC version, you may need to wait a while. Alternatively, select "Start" from the main menu, and go to "start from chapter 3 (before route selection)". It'll skip the beach event you're supposed to watch, but put you at the end event of the route.
...HOWEVER, it should be noted that 41 levels is not necessary to progress. 40 is enough. Please check the bottom left corner of the screen as Satoshi, there should be a big button that reads CALL ARATO.
I'll be adding a way to make this more visible in the future, as a lot of people seem to have trouble finding it.
Is it not allowed to share save for this game? I lost my save and starting game from zero is painful. Why nobody share their save? Nobody has a full save or save from last patch?
If you want to start from last patch, simply choose "Start" on the main menu and select to catch-up to current update.
EDIT: Simply copy and paste the "game" folder into the King of Summer's folder and replace files as needed.
