Overall its a great game, perfect for the theme. I have a few minor issues with it though. Often, I would make a shadow that quite accurately represents the required logo, but the game wouldn't recognize it. I'd have to spend a good amount of time playing with the rotations to get it right sometimes I would have to rotate it 180 degrees on an axis to get the 'right' logo(which was identical to the one I got before). I got the downloadable version and the game was cut off on the bottom and right sides in windowed and full screen mode. It didn't affect gameplay though.
I would recommend you uncheck the option "Automatically start on page load" on the game's itch.io page as the game starts loading when you open the page and takes a lot of resources.
