The game is pretty good but it has some tedious flaws. First the controls. For the most part they work just fine, but some of them could have been given a different key command. The dash move for example: could have been given a letter key command instead of the right arrow key while in the air. The reason why I say this because often times I have tried to control my momentum while in the air, especially if it would have helped to move forward just a little, only to make the dolphin dash forward making me miss stars. This probably wouldn't be as big of an issue if the autoscrolling wasn't so fast. That's the next problem. The autoscrolling actually moves faster than the dolphin does, which results in me wanting to just move forward while in the air without dashing since that often leads you to missing stars if there isn't a straight line of them for the dash move. The sonar move is also a problem. Not so much for the fact of it not working, but some of the areas where you must use it are very inconvenient. Especially after taking a dive to quickly get stars from below you, only to miss sonar stars if you don't have split reaction timing. I feel like the only way you can beat this game is to remember the star patterns through constant trial and error. I did manage to beat it, but after many attempts, especially around level 17 and up. The dolphin animations are smooth, the backgrounds have some pleasant artwork and the music is decent. Overall the game is good, but it had a lot of potential to be a lot better.
