Midway Arcade Origins

After many attempts I finally got it by doing this:

Default controls
Every time the river has land in the middle I stayed left. If I went right of an island once the ach didn't pop.

The ach popped as I crossed into the second river.

Edit: It seems you have to be ahead of the AI when the river splits or you will be forced to go the way they went.

Just finish the first level in the game without hitting any of the obstacles. It sounds easy but can present a challenge...but practice will be valuable, as everything is in a static location and doesn't change from game to game.

Things to avoid:

-Branches
-Fishermen
-Fallen trees
-Falling rocks
-Treasure (unless you want the points, but they won't help you really get the achievement)

You can run across the rocks, they'll only slow you down. Bumping the edges is ok, too.I've found that a good tactic here is to let the AI controlled player take the lead once you drop down the second waterfall. If they hit the fallen trees, it'll remove them from the playing field. They'll run out of lives eventually, but any help here is appreciated.

When the trees fall, if you hang back long enough, you pass easily close to the shoreline.

Cans can destroy some obstacles, but I personally found it easiest to avoid everything, as it helps keep you focused on what's coming up.

Just take it semi-slow and steady, and avoid mashing the buttons to avoid obstacles as much as possible, as it almost always ends in losing a life. Just don't stall too much, as the alligator will come after you if you hang about.

I cannot stress enough how much easier this is if you use the d-pad to move, also try mapping the "throw" button to A, that way its easy to move around, and use A to throw cans to get rid of any obstacle and its so much easier. As said in other solutions stay left and move at a steady pace, DO NOT hang back as the crocodiles will creep up and ruin it for you.

Hope this helps.
