It is a bit annoying that the game does not indicate when I should click for scene to proceed, and when I just have to wait.
And often, sprites move too slowly and pauses ('thinking', between animations & transitions) are too long. These little transitions are cool when you see them for the first time, but the game has plenty of scenes I have to repeat. Waiting for the bartender to sloooowly walk for the beer isn't fun.
Ren'Py has a built-in fast-forward function, but in this game it's rarely available.
