While I was playing Bubsy 3D last night, playing the only worthy level, the second one, I found an area where you can get up so high, a height of UE with the coordinates cheat, that, upon jumping, the ground can easily be seen fogging away.  It's in the mountains near the end of the level marker.  As you face the area with the electric enemy with the fan leading up to the final platform visible, it's the area in the mountains a little to the left from there.  It's tricky to get here as you need fine jumping skills.  I've been up 5 times higher though with the help of a fan in that same level, one of the many bugs I've found.  It was by using this bug that I was able to get here quickly.

Why do I bother doing this?  I'm always attracted to high places, trying to get as high as I possibly can.  I first start playing a game like one normally would going through the levels normally.  When I'm done, I begin making my own challenges and getting as high as I possibly can is almost always one such challenge.  By making my own challenges, I can play games for a much longer duration and I still play games I've played for years.  I've probably played Bubsy 3D for about 700 hours in all, 2/5 of that in the second level and 1/3 in the first level.  The rest for the other levels which are much less liked since I'm not able to make up my own challenges anywhere near as much as the first two levels.
