Awesome!
Good:
-Cute graphics
-Separate mute options for music and sound effects
-Music and sound effects are good
-Gameplay is simple, intuitive and fun.
-Generally pretty addictive! I played basically nonstop until I caught the Kraken.
-Autosaves frequently.
Needs Improvement:
-I noticed some lag the more fish there were - this may be partially on my end, so no points removed for it, but it may be something to check into if other people have had this issue.
-Too short/no satisfying ending. I really wish there were more upgrades - as is, once you've rescued the dad, there's not a lot more to do - you don't even get to take the Kraken home and mount it as a trophy or anything, and it feels like it ends a bit too quickly.
-The arrows indicating which key to press when catching some fish could be kind of hard to see. This was especially a problem when catching the Kraken. I'd make them stand out a bit more.
-While not a high priority, some medals for some of the trickier things would be fun - catching a boatload entirely of whales, etc.
