The game seems to run just fine on my laptop. Though, I think my laptop may be kind of powerful as well.

I like the style and gore of the game. When you kill someone, they turn into a mess of blood and unrecognizable body parts!
I don't know how to chain attacks together. Can you add a tutorial on that in the game itself?
The visuals in the menus look as if they have been artificially pixelated to fit with the pixel art style.
The enemies do a lot of damage and with little warning. This makes the game feel kind of cheap when you play for the first time.
I didn't actually know there was a health meter in the game until a few minutes after playing. I'd recommend moving the health meter down to bottom of the screen and making it contrast more with the background. Perhaps a healthbar? (Though if the player can gain health greater than 100, a numerical health meter would work out better)
Is the main character a little girl? The player character in-game looks like a little girl, but in the menus, she looks older. Is this part of the mystery of the game?
The time between dying and respawning should probably be shortened.
I'm not fully sure what the enemies were supposed to resemble until I saw the death cutscene. Are they wielding canes or arm blades?
I always feel bad writing long lists of suggestions. Makes me like I'm being overly critical of someone work. :(
The game looks pretty good at the moment. I think you have a good start here. Can't wait to see how your finished game will look! Keep it up!
