Ok first things first- this is an unity game, and that means you can do a web build. Web build allows more people (like lazy ones, to whom downloading is too much of a hassle, or ones who don't have windows machines, or the ones who use work pcs for games) to play your game. Seriously, try it...
because your game is great! Seriously I could go with how good everything works together... and I guess I will!
Graphics, animation, presentation- great. Animations sold the attacks, the particle fx and sounds gave good feedback on when the player or baddies get hit. Difficulty went up gradually, and felt fair (I had to repeat second level twice, but because I played bad not because the game glitched or something). You had actual levels, a plot, and a boss. I can't stress enough how I liked this. I know, with the time constraints a bunch of people went for an endless or wave base games, but I'm a guy who loves levels. And bosses! Especially if they call in minions during the fight! So much so, that I also have it in my game! (yeah, call it shameless self-promotion!)
If I had to pick the things I didn't like, not much comes to mind. Movement speed could ba a bit faster maybe? And I don't see a point of rolling, because you roll exactly the same speed as walking.
To end this comment- this is one of the best games in this jam. Seriously- you rarely see jam games, where everything just works together, but you did it! Keep up the awesome work!
