This game is a mess, I wouldn't even know where to start counting just how many missing flags there are. A lot of times prerequisites are missing and as such seemingly random things which haven't even happened yet are being mentioned in various events. As if that wasn't already bad enough, the quests often fail to mention the prerequisites which are actually in place, which can make it very difficult to progress. The game offers sandbox elements but oftentimes it feels like the choices are locked because there are prerequisites in place which are impossible to know of if other quests are postponed to be completed (e.g. lack of interest in a character or waiting for a better moment). And since I mention prerequisites, forcing the player to wait for certain days to pass for almost every quest makes it a worse experience overall. Waiting for certain days should only play a role if certain events are automatically triggered on that day, not to force the player to wait just for the sake of it, otherwise it's just as bad as being forced to grind.
The quests should properly mention what has to be done to continue, a main quest tracker would also be a good addition, though before that the prerequisites need to be fixed to include all preceding events. This is a sandbox game but it often feels like we can only choose the order in which we would like to do things, not what we actually want and do not want to do, which also leads to the issue that characters are forced upon us or even have to be corrupted without us choosing to do so.
The gallery and replays are similarly messy, they are just thrown together, it would be better to properly split them into important characters, side characters and others. There aren't as many replays as there are images in the gallery but it still is somewhat tedious to scroll through to find what you are looking for. Without relying on some kind of gallery/replay unlock (mod) it would also be nice if conditions for unlocking them would be listed, partly due to what I already said above because everything is a mess.
This is probably more subjective, but why does corruption have to lead to excessive make-up? In my opinion it makes characters (at the very least) less appealing.
