Super Meat Boy/(Cartridge Dump)

1-1
This takes three jumps. Hop over to the first square. Wall jump off the right side of it, slowing your horizontal movement so the apex of your jump reaches the bandage, and land on the second single-block platform. Depending on your timing, it may be easier to bypass the second single-block platform as you are falling and continue to the right to hit the very bottom of the final platform, which you can wall jump up. Otherwise, hop over to Bandage Girl.

1-2
Jump to the first small platform (do not try jumping from the first platform). Run and jump the long gap to the second one and wall jump at the precise moment you hit the wall, otherwise you will die (if you are doing a speedrun, you can bypass landing on top of the third platform as you wall jump up). Make the easy, final jump to Bandage Girl to finish this level.

1-3
Like 1-1, jump up to the first platform. Wall jump off the right side to get the bandage and cross the gap to the second platform. Wall jump up if need be to save yourself. Hop down to reach Bandage Girl.
