Strange
The ocean theme doesn't seem to have much connection, but it is a genuinely tricky game. I only played through once, but I get the feeling that once you get some experience using all four of the whales some high scores can start stacking up. Personally the most I could manage was two words going at a time, but it was nice that the letters scrolled fast enough that you didn't have to sit around waiting too long for any particular letter.
A highly original and challenging little invention you have here, I'm surprised it hasn't seen more interest.
