Game was a lot of fun and has a very clever idea. Arena mode didn't seem challenging at all if you just stand in the middle and hold click.

Very nice concept!
The physics feel pretty nice at the start because it feels like the sword is heavy, but later it's kinda weird. Also, this can happen: https://imgur.com/a/23FqV

The victory screen is kinda sudden, because you don't see the boss die.
You can stand still next to an enemy, and after the first hit you won't take more damage at all. This coupled with the long health bar make it very hard to lose.

i liked it a lot pretty funny physics very fun but it didnt fit the theme "the more you have the worse it is" very well because the bigger sword you got the better it was so there was that otherwise great job

Nice idea and great controls. Just swinging and running around is quite enjoyable.

This totally was the swordest sword! +points for the name. The visual feedback could be a bit more comprehensive. I liked the gamepad controls much better, that's why I played both WebGL and Win. It took me 3 tries to win :D Congratz on putting this together!

I love the sword movement. Graphics are simple and cool. Theme link was tenuous. Audio wasn't there. Hard to tell if I was being hit or hitting with the particles. Having a score or record of achievement would have been awesome. Inclusion of arena mode was great, although I found arena much more difficult. Overall a really interesting entry.

This is awesome, It felt really responsive swinging the sword around, I'd really like to see some audio for it, even just some simple sound effects would make it a much more enjoyable experience. I only had two issues, the first is that the enemies don't seem to die immediately, making staying alive incredibly difficult, and second, i managed to lodge the sword backwards through my body once, meaning I had basically zero range and died super quickly. I'd really like to see this idea expanded upon a lot.

Excellent idea for a game! Hack and slash with a side of puzzles... I love it! Game's a bit tough, of course, and I only caught a glimpse of the last boss before dying... And running through without killing seems to be quite difficult as well, but at the same time, with a blade too long, it gets even worse! Good job!

Yeah, an interesting idea! It was fun to run through the last tunnel with a large af sword piercing all the enemies on the way.

A bit sad that there was no audio though :(

Allow me to throw some ideas and opinions into the ring :D

-To solve the spin to win mechanic abuse, use two "stamina" bars that represent your left or right swing. When one goes down the other goes up, a simple balancing act that encourages creative play. (when not swinging they'll gradually return to equilibrium)

-Remove the delay of enemy death and/or add some knock-back.

**You have game with some great potential,** I'd love to play and/or work on it :p
