I like the idea a lot; I was not too fond of the way you have to play, lol.
You have to move around the screen frantically, and I wanted to spin the sword around constantly to do damage, but I couldn't even swing it at all while moving. It's too much to manage at once; I would prefer it with a click-to-attack or some other mechanism.

I think it has a lot of potential with some playtesting and tweaking, though; great job!

Great idea! Like a very sharp, stabby katamari. Nice and consistent art too, good job!

Simple fun, tho the mouse control was quite weird and I think the camera/scroll glitched midway through

I really enjoyed this game idea! I do believe the left and right turning of the sword was a little stiff but this premise is so insane I hope it gets an improved iteration!

Simple and fun concept

Simple Idea with great execution, I wish there was Q/E for turning as well, but despite that I had a lot of fun. Unique idea too! Well done :) 

Picking up everyone's weapons and slowly turning into a rotating death ball is very fun, and it makes it really satisfying to kill the enemies. My only real complaint is the controls- I kind of wish the sword would just follow your mouse at any speed, since right now it's pretty unintuitive. Still, the core concept is really strong, and the art and music are also really polished, so I had a good time. Good job!

Very difficult to control the sword swings, especially when moving. And since the enemies are relentless, you're always on the move. The level also scrolls a tad too quickly for me to pick up weapons dropped by enemies sometimes. Nonetheless, really fun concept and a blast to play otherwise
