Commander Keen 4 any% -

Commander Keen 4: Secret of the Oracle version 1.0 shareware, DOSBox version 0.74 at max 100% cycles. The purpose of max cycles is to minimize in-game loading times.

Start time is Keen's first frame of movement on the map; end time is Keen touching the last red-robed guy (in the water level), which is noted by the first frame that doesn't indicate movement after reaching him. Note that, by a different (and usual for other runners) timing, this time should be ~0.25s slower: I'm just using what I consider a slightly better starting point for the purposes of frame-count.

The messup in Crystalus costs a whopping 1.5s, but it is the only mistake in the run: everything else is "less than optimal" and in many cases not by much at all. Oracles were nice enough, I guess. My theoretical best is six seconds faster, and probably 2-3s of that was lost to bad oracles, so yeah, I'm generally satisfied with the movement in this run.
