Nice work!
Quite unique to be honest. Music was nice too.
Scaling was a bit messy and weird but it works. Completed all of the levels but I did take help on the "IsReal" level, I couldn't figure out when you could actually toggle, maybe add some colored boxes on where you could actually toggle or even make the is real button greyed out when you can't and make it green when you can toggle.
Another problem I ran into was dragging. Sometimes the ant would leave behind the page and I believe it's because the mouse cursor is far away from the paper because this doesn't happen when it's close.
