Looks like we had the same take on how to use the theme :) I liked beating up the blue octopusses, the particle effect was satisfying. As was dashing into them and making them bounce around.
Controls were good for the most part but felt a bit unresponsive, try making the attack and it's animation faster as well as making the player move faster. It's not bad from the ground up just needs more tuning I feel. Strong package overall!
