Nice work, engaging game but wow the difficulty is brutal, you need to be perfectly accurate with your cuts, if it's off by even one degree you are done for. Couldn't get past the fish steak. I definitely think the difficulty could be balanced a little better.
It's also possible to get soft locked if you make cuts that produce too tiny pieces which can't be clicked on. I think an option to restart whenever you want would be good, as well better feedback as you're cutting, it's very hard to tell if the pieces you cut are small enough.
By the way, I experienced some visual glitches in the beef cake level. It wasn't game-breaking but definitely a little distracting.
But overall compelling, this is a challenging puzzle game.
