Fortunately the basic enemies aren't too hard on their own, so take care of them with your bullet dispenser and head back up towards Gary's 'landing site'. You should be in the tall room you had dropped down in earlier, but now it has a bunch of occupants that weren't there before, and they aren't all that nice. Once they are taken care of, the gates will open and you can continue to the left. Just shooting them three or four times ought to do the trick. Thankfully the enemies in this room should be pretty easy for the most part, just be aware that if they see you, they will rush at you in order to attack.

There will be many of these types of 'Gate Rooms' throughout your run, so get used to them. Your only option here is to attack and destroy all of the enemies inside the room in order to open the gates back up. Walking back into this room activates a couple of lock gates on both sides of the room, trapping you inside. Your only option is to head back out the way you came to the left. Fortunately it has been pretty quiet, but you can't stay in here forever. As a bonus, you'll jump inside a Mech Suit, which enables you to now shoot any enemies that crop up on your quest. I know it's been a horribly long journey so far, so it might be a good idea to take that opportunity and jump on the platform on the left side of the room to do so. This is your very first chance to save your game. You'll eventually reach your destination in the next room. Nothing difficult here, just some really basic jumping. Make your way right, jumping over anything that happens to be in your way. On your right, you should see the entrance to the next room.

Don't worry about running into any enemies yet, just keep dropping until you reach the bottom of this particular room. Keep going down this room until you reach the bottom floor. Ignore that for now and head down the hole in the floor. Jump out of the water and you should see the first bubble door in the game on the left. Turns out Kiki ain't afraid of no water and jumps on in, so continue left until the room pans. Here, another short cutscene involving water occurs.

Start by heading left, wall-jumping over the first obstacle that you come across and get to the next room.
