I had some trouble with the WebGL so I downloaded it first. However, I tried it again and it turns out your WebGL is just not displaying a load screen or anything so it just looks like a black screen to me for 30 seconds before it plays so I thought it was broken. Tried to trouble shoot it for you but IDK. I turned off all my blockers and use Chrome, which I assume you do too, so I don't know why it's doing that. Anyways, the onto the game.
The graphics are very smooth. I'm great music for a Compo game. Most Compo games are missing that, as it is tricky to make your own tracks in on top of everything else. I got a lot of joy from cutting up the papers. It took me a try or two before I realized the trick was to click like a manic, then the game is easy. I did not care for the standard cut size. It made my strokes short when I tried for long and it made my cuts too easy by just by clicking. I would almost do away with the cut mechanic and just have the documents slice up if you click on them. That is pretty much what I was doing anyways. Good to try new things though.
Anyways, here is a link to my Compo game if you would like to return the feedback: https://ldjam.com/events/ludum-dare/40/squirrel-puncher-4000
