A really unique idea for a theme and gameplay loop, one that I actually really enjoyed. The visuals complemented it well and the audio was amusing while not overstaying itself. The RPG mechanics are fun, and it would be interesting to see where that would go, larger swing arc - other ways of attacking - etc.
The gameplay itself however could've used some more polish, it was difficult to get the flail to move in the way I wanted, and the player would sometimes not rotate enough to swing. Being the primary control and way the player interacts with the world, it would've been nice to streamline. My arm started hurting from moving my mouse around in circles.
Overall a really great idea and executed well, needs just a tiny bit of adjustment to be really fun.
