Fast 'n' furious maze collect 'em up in the Gauntlet vein.
For infinite lives, re-define the keys as E B O R P (in that order), and then re-define them again as you want them for game play. Then when you play you have infinite lives.
Screen One:
First, whip the left hand brick out from under the guard as he walks along the platform. Then press duck/fire, fire, duck/fire, fire, duck/fire, fire. Get the key and work your way to the exit. Get the gems on either side of the screen if you must, but don't worry about them. Enter the centre block from the side and get the three trinkets, not forgetting the other three hidden in the brick underneath. Then wait for the bird to bounce off the wall on your side and pass you, and jump on the platform behind him and scoot to the exit.
Screen Two:
Step foward one brick and press fire. The animal will walk towards you and drop down the hole. Press duck/fire and step foward and press fire. The same thing happens. Now press duck/fire, step forward, jump/fire, fire and the creature will fall down again. Now repeat that last sequence, and the creatures will begin to fall down the hole. Cross the gap by placing a brick in it, stepping over and then removing it agin. Then you're free to get the key and get out.
Screen Three:
First, place two bricks in the right hand corner of the compartment. Wait until the fireball goes over your head, then jump fire, jump, fire and you're into the next bit. Go through the wall and press duck/fire, forward, duck/fire and then jump over the first spider as it comes for you. Wait for the second one to go through the tunnel you just came through, and then seal it. Jump down past the bird, get the key and release the spider, jumping out of the way to let it pass. Jump down into the next bit and shoot a fireball at the guard. Get the bag, and headbutt the brick under the bird. Get the trinket and climb up to the last bit. Wait until the llamas leave you enough space and then duck/fire, forward, fire, jump, duck/fire, forward and duck/fire - then you're in.
Screen Four:
Well, yes. Okay, so you can walk straight across, but it's a good idea to spend a little time rescuing the angels at the top.
Screen Five:
Very tricky. As fast as you can, drop a brick in front of you, back up one and drop another brick beside it (the devil will drop down on top of you if you don't!) Build a little staircase to the top spider and then build a bridge to his brick. Let him walk across it and jump over him, destroying the bridge behind you. Jump and steer yourself underneath to get the key. You'll probably get kill if you don't get off floor level as soon as possible. Otherwise, make a staircase again and this time go up and over the spider and drop down into the exit.
Screen Six:
Gotta be fast. Wait until the bird bounces off the bricks and the devils drop. Press duck/fire, forward, fire, jump, fire, jump, fire, jump, duck/fire. Wait till the birds are out and drop down, aiming for the key, then aim to miss the eagle. Turn and shoot it with. Get the bag and the gem and make your way carefully up to the exit.
Screen Seven:
Get the fireball bug, and make your way up to the key. Having got it, you must place bricks repeatedly in the way of the fireball being thrown by the eagle, and leap up and headbutt the bricks in your way. Then in between fireballs, jump up and over the devil generator and drop down behind the eagle into the exit.
