See the block right at the start? I wonder if a lion knows how to jump that high... You can tell you need to move that blocks in their grooves to get anywhere. You also knew you'd have to get up on those pillars. Line up the block to the shortest column and start from there. No, really, that's how you do it. Seriously, go try it again. Now hop up the pillars to the ledge on the top of the wall. Whatever happened to those peaceful swims? If only there were some place to hop onto a ledge and shoot at the alligator. You thought you knew your jumping skills. Welcome to hopping hades. Explore each story thoroughly, but don't expect a lever on every level. Expect to do some backtracking. Also make sure you remember where the named rooms are. The rooms themselves are pretty easy. Take some time to look around. Don't worry about a little jolt in Thor's room, it can't be avoided. You don't want to be standing still when the hammer falls. You might want to do Neptune's room in two swims. Towards the bottom the level the baddies will reappear even once you've been there. Look before you leap.
