I love the addition of the starfish! I think they are very powerful and let you get much further, but they take some brainpower to use. They can be very useful as a deciding factor: when there are a few possible squares where a jelly can be, they can show you which you should flag. In addition they are powerful when they are absent, because you can determine that certain squares cannot be a jelly, because there would have to be a starfish if it was. It reminds me a bit of solving sudoku puzzles ^_^

The change with the shells is really nice too. I like that they are now a complete positive; they both give you a drain and they give you useful information. Although I feel like I get quite a lot more than I actually need

I have no idea what you would need a mute button for, because the music is so awesome, haha :P

One thing I noticed while playing this time is that I accidentally let the water reach the top, even though I had enough shells left over. This felt a bit annoying, because I could have easily prevented it if I had payed attention. On the other hand, automatically using a shell when the water gets too high is maybe also against the idea behind the game :/ This is not really criticism, but just something I noticed if you are interested ^^

The last thing to make it complete I guess would be a nice tutorial in the game, but that may be quite tricky as there are quite a lot of rules.

A very nice update! Thanks a lot! I enjoyed it greatly :D
