Collection of ideas for scrapped KS levels, or those I don't know if I'll ever finish.
Knytter: Exploration level with the red/blue switch mechanics of REDDER. Never made a single room for it.
Hourglass Shape: Level where all of the rooms were arranged in the shape of an hourglass. Would feature a part near the end with seemingly unscalable overhangs that would grant you an easter egg if climbed. One of the few rooms I made for it would later be used as the starting room for garden.
Columbo: Juni wakes up, goes to her workplace to set a disguised explosive under the desk in her cubicle, works her shift, then goes back home before the bomb eventually explodes. You'd be traversing with no run powerup through a boring flat landscape both to get to work and on the way back. Entirely meant to riff on one particular Columbo episode with virtually the same plot where it took from the beginning of the show to the first or second ad break for this to actually happen.
crate pushing level: Shift-based level that would have played like a side-view sokoban with gravity. Juni would walk into the side of a crate to "push" it. Abandoned by the second screen.
flambe level: Another shift-based thing. The foreground and background are both transparent, only the foreground is solid. Shifting would cause the foreground and background to switch places. Combined with KS+'s Overlay=True feature, this would make it look like the shift is actually sending you between the layers.
minimalistic closer: Prototype of Get focus. I had almost the whole map layed out, but never got around to A) finishing the final area or B) actually adding the "closing behind you" effect.
Space is Cliche: Dr. Cliche's lab in space. The whole gimmick was that you'd occasionally exit the safety of his various rooms and tubes, and a timed shift (plus a custom object that resembled a timer) would kill you if you were outside for too long.
Will post more.
