Very unique idea for your game! I never thought of using a banana for a ruler. The first time I played through, I never picked up the saw and got to the end, but when pressing play again, the blueprints would say "part 1 / null" and 1 / what just kept counting up each time. After reloading the page, I actually cut out pieces, but after the third level I wasn't able to go to the following screen (the next blueprint button couldn't be pressed). Cool idea, just needed a bit more playtesting ;)
