683k feet. *curseword curseword curseword*
It was an AMAZING run. Somehow I hit a cannon and got up to 45.000 feet. He was up there for ages! I took a screenshot and unfortunately used one of my hits because I had to click in the game again. By the time I had to hit him for the first time, I had flown 500.000 feet. No sweat, right? WELL SWEAT! I miss two hits, and was generally unlucky, and landed just 17k feet short of the achievement.
The bowl wasn't that hard. You need to identify where the creeper builds up, and start shooting at that point before it flows over the top. On The Bowl, the choke points are below the left and right emitter. You almost only need one blaster at each location to keep it at bay, and then you can spread out with a few more blasters.
