Failed due to exceeding the time limit (´･ω･`)
I think in the actual test, without Gambit, it would be impossible for everyone to finish within the time limit.
The broom stickers, in particular, are hell; they take about 10 minutes just for that, so if you haven't gotten this far with 10 minutes left, it's over.
I think it's also an option to put them on first, but if you run out of time and can't finish the main body, you'll fail, so I think it's better to make the main body and pass, even if it's not a perfect score, without the stickers.
Looking back, I even forgot to put on some stickers, so you really need to cut them quickly and make it as fast as possible without resorting to ulterior motives like sanding, otherwise you won't get a perfect score.
