This is really getting good now. The more I play it, the more I like it. (I got to level 5!) The sonar visual effects are really good, the sound is good, the bubbles look great, and it's a really good game idea. That reminds me: I think they are showing "Das Boot" again on TV here soon... (Or should I rather watch "Red October"...?)

Hey, I got through! Took my a while to beat the boss, though. (I liked the old front screen graphic, though. Bring it back - we need a 'classic' version with the original artwork!)
