I tried to play JP, but only had to realize it has an empty playfield ala Stern's minimalistic approach, where less is less
The only exception was the dinosaur in the back, which was semicool.
Should not be a TOP-10 game IMO. Have to go and give ratings to that game.
EDIT: Actually, what made the game cooler is the user-led project that created new video/audiofiles for the game. JJP could learn something from it...
