there is a glitch on swimming training so open 1 more tab so u have 2 tabs one with the game and one more so click play on swimming training and then switch to the other tab and the duck will go through all obstacles so when ur done switch back to ur game and u have free swimming level (try this and press + so everyone can see this!)
