There's another trick if you read some of the various readme files that come with the game/saves, but it's not 100% so I won't quote it without the caveats in the readme.
The rightclick is introduced a year ago? We pester Nenad with bug reports if this function isn't working. Also Nenad knows what the possible problem is, so new version usually work fine. Nowadays I don't even think about it and use rightclick every time. In some locations this doesn't work and now those are filed as bug reports
In the previous version Nenad introduced another shortcut which makes the right click even better. For example on the dock were Gloria's yacht is, you move the mouse to the right until you see the enter yacht option. However when you move the mouse back to right click it, the camera focus did go back to Willy. Now by pressing 3 -- 4 focuses the camera on Willy again -- the camera focuses on the mouse pointer which means even faster walking. Now I manage to dodge Giulio more easily, while this was always difficult with the chaotic camera focus.
This new function doesn't work in all locations yet, but again those are reported as bugs.
Anyway I didn't answer V01 or pablo_max because he/she clearly didn't read the documentation. Fine if you don't like a game, but complaining about things without research is just wrong.For example the unnecessary file size? That's an opinion without reading and researching again. I see that Ren'py games lately are also have a very noticeable jump in file size because of animations. Willy has at least 500 if not more of them. Plus they use more images per animation.
