Yes, you can do that, However i chose not to i MY game. The games just supposed to be a joke anyway. So is 'Crossing Bridges', Infact, i only made that game for the people without a sence of humour wo said "Make a harder game next time". So i did.
Darksimal, it cost nothing, except 10 minutes of my time. I can't be bohered to find were i downloaded flash, just google "download flash" or smeting like that, and I will not be bothered to work out he combinations either. Havermorphism, Its not due to an odd number of bridges. If there we 3 bridges,you could still cross them all.
