For some reason, the flight I was on didn't have all ten levels, only the first five levels were available on my screen and the game over screen would occur once I beat the fifth level. It seems like the build of plane only had the first five levels available but on my next connected flight it did have all ten levels and I noticed the plane looked a little different and probably was an older build. So I'd say add a Half% category for planes that only have the first five levels.
On the next plane I was going to crush Headflushed's record by a long shot as for some reason I decided to torcher myself and start reviewing all the levels and memorizing all the locations of the items. But by the time I was ready to do so, the plane landed and that was my last flight for this summer, maybe next summer I'll beat Headflushed's record, who knows. For now this is good, I'm going to submit this and some ILs soon.
Mod Note: I now reverified this so the half category can be added.
