Half of the battle is learning how to read the walls in the tunnels. With practice you will soon get to know them and since the game does not get any harder in the long run, simply repeating already familiar wall patterns. Once you can hit 2-3 million, there really is nothing stopping you multiplying that by a factor of 10 or more. I do remember that in the early 90's Mr B's in Blackpool it used to take me a few credits just to get my eye in again due to not having played it for 6 months or more.
"Use the force" if you want a nice boost to the score, but BITD my main boost to scores was shooting all the towers in stage 2. You can get all of them in every wave, but there are a couple where shooting all is just too risky and not worth doing.
Fatigue was the main enemy when I played it in the arcades, and I ended up sharing a game with my mate most times, swapping out after we each cleared 1 Million points.
Incidentally,. the WR is twice as high as the best score I ever saw in Glasgow, and 8-9 times higher than I ever managed back then.
