We have received bug reports saying that players cannot unlock all CGs and achievements despite reaching the end of the game.
This is not a bug. Although Sloth: Heart to Heart is labeled as a kinetic visual novel and has no choices, it has multiple branches with unique CGs for each. Those branches can be unlocked via a hidden mechanism. To not spoil the fun, we have decided not to reveal how that mechanism works. The player needs to read all those branches to obtain the “Unlock All CGs" achievements. Moreover, not all branches lead to an ending, some lead to a dead-end. That being the case, the player needs to finish a branch that has an actual ending to unlock the “Finish Heart to Heart for the first time” achievement.
Hopefully, this clears up the issue that players are having at the moment.
Best Regards,
