It can't be compared with any other game to my knowledge.
This is Gonta the Diver II
(I don't know where is part I)
We will play the us version : short name = prtytime.
(Japanese clone=gangonta)
AND we will play for WCC only on NORMAL MODE
(you also have a practice mode with 3 girls and explanations --that's why I choose the us version-- on how to play ; better start with this to learn the game)
Special bonus :
10 pts for first inp to finish the game
(9 girls with 5 levels each = 45 levels)
Before Destructor grunts :
