I'll start with this, and this is really important (not affect on rating, just an advice). You made an Unity game. Click that build options, and make a web build next time. My first game, where I did a web build had more plays than ALL the games I made before. Seriously- people view downloading games as a hassle, and Web Build just boosts your audience so much.
Now let's talk about your game!
Let's start with obvious- really nice graphics style, cool animations. Controls were rather responsive, I knew if the attack would land or not. Music fit the atmosphere, all good stuff.
The game needs a score displayed at the end. I beat all those dudes, and didn't even know how good I did.
A bigger thing is something else here, and this is a problem several games in this jam have. It's pretty good, I just need MORE of it! Like, more enemy types! Even slower guy that hits harder than normal guy, but has (for example) a red shirt, or different hair, would be nice! And you know what else- those beat-em-up games rally beg for a boss at an end of a level.
What I'm trying to say here, is my personal preference is a level with a boss at an end to the endless barrage of dudes.
