Asterix (Sega)/Round 2–3

Head to the right, avoiding falling flowerpots, and jump on the spring. In this area men appear at the windows and push you with their hands, making you fall backwards. You can safely stand on the far left edge of the window. The men alternate, so if a window in front of you has a man disappear the one you're on will soon have a man. The next floor is much the same.

When you reach the next area, head right, smash the wall down, and collect the mud potion. Head to the right, using the mud to make platforms. Except for a gold coin and a crossbones these blocks are empty. Whack the man at the end and head down. The middle part of the blocks in this area contains a helmet which you might want, but otherwise just continue left. You now have two routes, through the door or down the ivy.

Ivy
Step on the block and quickly head left before the other one lowers. In the next area throw mud at the man and jump on his head to reach the upper platform. Head to the right, jump up offscreen and continue right. Here you'll find meat, a bag of gold and a crossbones. Head back and through the door. You'll end up in an area with a pot spewing loot all over the place. Simply walk around collecting all you can. You'll see some little lightning-spewing men. They are invincible and easily avoided (when their faces light up they're about to throw lightning bolts). Eventually you'll reach a door. Go through it quickly, or the forced screen scrolling will kill you. Go through the door and you'll end up underwater.

Underwater
Swim to the right. Paddle in the middle of the starfish things to avoid damage. At the end, swim up then head right. The blocks here contain a bit of loot, and the one in the recess contains a helmet. Head through the door.

Hop on the platform. When the wall on your right ends the platform will soon disappear, so jump across onto it. Once there jump as far to the right as possible. Blow the bricks and the pot and collect the key. Fall down and unlock the door.
