First observations:
Great layout but with 3 SDTM drains, one can be fixed with a thicker post rubber, the other 2 I'll have to see.
Scoop is way too easy to hit, the entrance needs making smaller.
The playfield villians, the top one is labelled aka Mr Henderson but shows Blofeld. This is plain wrong and can't be fixed (except for an overlay) as bad as the DE Star Trek where is said JACKJPOT. No amount of code can fix this travesty.
This same mode is still Bath-O-Sub whereas it should be Bathysub (from the greek for depth IIRC), just horrible to look at on screen.
Code, well not going to comment much as it's way too early but it could be a great game and we'll just have to wait and pray Lonnie does more that he usually does...
