When I do point-to-point or a Vero board layout I find it helps to plan a layout carefully in Eagle first. You can download a free version that limits the size of the board that you can use but it would be plenty big enough for this project. The learning curve of the app is not too huge - you first layout a schematic and choose part sizes according to what you plan to use, then move the parts around until you are happy that their leads can form the circuit easily enough. If you are clever you can also lay parts on both sides of the board to get them nice and close.

there's a dead bug in the middle of my amp, and it's ...well, actually sounding not too bad.

Try to keep all paths as short as possible and decoupling close to chip on veroboard.
