Great idea for a game. The graphics are very nice now. I especially like the bubbles. Seems a bit hard to navigate from side to side. Maybe you could gradually slow the ship down when no key is pressed?

hmm, i afraid if i add a countdown timer the game is too hard i just thinking any pressure :D (sharks, moving blocks, volcano :D) hmm, but the i put the countdown, but invisible (not have counter, bar and others) ^^

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"...?)

sonar inspired from, 360 degrees shoot i made in MiksAsteroid background i made with paint.net sound download at soundsnap.com bubbles... eee.. paint.net ^^ yes ! level 2 was very "hard" :D

Finally got to download and try a few greenfoot games last weekend. Sonar Way has a lot going for it - good job! Looks like you've been working on it for a while. Not for anyone looking for a quick diversion though.

thanks ! this game just spontan idea the basics create of this game less than one week but i created to level 10 eat more time ^^

I'm not sure if it adversely affects the game, but in the sub(Vector other) method of the Vector class you've got a bug. It incorrectly calculates the length of the resultant vector: this.length = Math.sqrt(dx*dx-dy*dy); should be this.length = Math.sqrt(dx*dx+dy*dy);

thx for seeing the source, hehe but it has no effect since i didnt use that method anymore (i should delete it) *the submarine movement is slippery as the result

Very nice game, like the concept :) I also like the bubble physics XD
