Love the concept and artwork. The execution felt wonky though. I wasn't sure when it was to supposed to be making small pixel cuts or the larger ones. And the game lagged a lot when I was using the long knife. Lastly, the music wasn't looping for me. It played once and then the game was silent.
And like the other commenter, I'm not a fan of the font either. It's difficult to read, and it doesn't seem to have a symbol for apostrophes.
With that being said, I do see the potential in the game. I'm happy you are developing it further.
