The timer to rewire the bytes into the system is a bit too short, especially having to lose out on 4 of them seconds having to erase the previous numbers and having to type in the new ones. It was fun till I ended up stuck on that and after trying about 8 times and failing, giving up entirely because of having to click to erase the previous numbers, clicking again to type the new ones and having very little time to do any of that. -_-
