Good fun! The endless brawler style works great, though I do wish there were some sort of point score or similar way of keeping track of progress. The art style is creative and well executed, and the simple gameplay makes it very intuitive (though the controls listing on the main menu was appreciated).
I did find a slight problem - holding the 'block' button prevents all damage, but while blocking you can still attack, making the game incredibly easy if you just hold it down, becoming immune to all damage.
