I liked the execution. Very pro, and much like Castle Crashers, which obviously has its roots in some other games as well. I liked the gameplay, very smooth and looked great. Wasn't a fan of the controls layout, only because on a keyboard I'm used to WASD to move. I didn't look for options, though, so no harm there. The fact that you have a soundtrack is awesome, not enough games put that effort in. Overall, very fine product.
Loss of 1 star:
Some of the fonts and menus seemed cheap in comparison to the great artwork. Rushed? Either way, they aren't too distracting but a little goes a long way! My motto is "Design so people don't notice". Also, I wasn't overly fond of the theme (was I fighting squids?) and aside from a new plot and characters, this didn't refresh the genre at all. Not a big deal though, still a fabulous game and executed AMAZINGLY. Bravo to you and the entire team. Lastly: I'm a casual flash gamer, so grabbing me in the some way was a challenge to begin with. I made it through the first bit before I lost interest, so you did a good job, but widening that audience would increase replays and potentially grab up more fans.
Overall, well done, hope I wasn't too harsh! Just one man's humble opinions, thought I'd share cause you guys deserve the recognition. Well done.
