Imaginative and best of all fun
The game itself and the concept is excellent. I'm glad that people are still creating decent flash based games which don't include stickmen fighting or shooting each other.
This game also offers great design boasting a excellent musical score as well.
I do think that the controls were slightly difficult to get the hang of at first, however after a while they are fairly easy to grasp. It is recommended that you play with a handheld mouse rather than a mousepad, as the game is entirely reliant on mouse controls (Apart from using the spacebar for upgrades)
The upgrading system works marvellously, on the simple grounds that the player is able to revert any upgrades that they may have purchased. This then allows that player to then decide what they think may be the best combination of upgrades, without having to commit entirely to a couple of sections, such as Size, Speed, Health etc
Overall I thought that the game was really enjoyable, and is fun for players who want to just smash boats and eat people, as we all do from time to time :)
