I haven't had a chance to play this 5200 version for this hsc yet, but I do know general Dig Dug strategies:
1. Start the level by quickly killing as many enemies that are easy pickins', and getting to a safe spot. Don't let them group and surround and get you.
2. learn how to dig under a boulder and sit there forcing the enemies to approach you from 1 side (if in ghost form) or from below if solid, dropping the boulder on them all. Big points + clears the board of those enemies quickly.
3. To pump fast, keep moving foward as you pump. Don't stand still and pump ever - its too slow. Moving forward as you pump ensures that you'll hit a 2nd enemy who is travelling thru the enemy you are pumping up. If you don't break the pump line by moving a little, the enemy won't get hit by the pump and travel thru and get you.
4. Once you get to big point vegetables, that is you main goal -drop 2 boulders and get the veggie. Don't worry about killing Fygars from the left/right (to earn 2x points for them) and don't worry about trying to kill enemies lower on-screen (they are worth more the lower you are) - don't worry about that once it gets past like 5 levels or so. Just kill the enemies, survive, and use the veggies as your big points. When your skill improves, then you can try to squeeze every single point out of a level.
