I have completed the 7 levels of R2, and can get into L8 but I can't get too far. I have found 2 entrances to the secret temple, one near the start where you use a super bomb to open it up and the other at the red grave. It seems I need the flippers now but can't move around any further in the temple, and am blocked by water in L8. Could someone please help me out? Tks
