| It's just so frustrating that I have to start over every time I fall.
This achievement is rather difficult and is considered quite hard. Due to its hard difficulty, the power cell reward for this achievement is higher than most achievements. Infinite Mode level achievements are usually not affected by this and they still keep their 25-75 power cell rewards if not affected.
This achievement requires luck, as not every level lets you stay on the bridge for 5 seconds. You should jump on the bridge from a normal tile, wait a tiny bit, then small jump onto the bridge from the bridge again. Stay there, for 5 secs, then jump from the bridge to the bridge again. Try to go again for 5 secs, but it's unlikely you'll make it. Either way, it's worth it to stay on the bridge, as you won't be penalized for beating the level. The type of level you would want is something like IM 230. It has narrow platforms with lots of gaps. When you get a level like that, you should take advantage of it, as you might not get a good level later on.
In older versions or on mobile, the achievement went as follows: "Jump into the endless abyss of space, only to have your descent arrested by the Flying Spaghetti Monster's holy light. To prove your trust in Him, do this 30 times in a single Infinite mode run."
