(Lake Marlarsee, Sweden)
At the moment you can fish any where you want but soon we will be adding the levels that will restrict you to have to begin at the beginning ponds.(Synodontis+nigriventris/ Upside down catfish)
I hate to say it but if you have fished so far your level will be reset as soon as the leveling begins. We are working on this and hope to have it ready soon, but want to make sure that everything is the correct, so we wont have to reset again.
