=== Staircases ===
To When pressing up in proximity of stairs, Simon gets pulled towards them and stars climbing the first step. It's possible to do this movement more optimally by pushing up while perfectly below stairs, instead of while in proximity.<br />When approaching stairs frontally (such as the ending staircase in stage 01), the timed up press saves time on a 2-frame window, where the first frame save either 1 or 2 frames, and the second frame saves either 2 or 3 frames. If late on the up press, 1 frame is lost if late by one frame, 3 frames are lost if late by two frames, 5 frames are lost if late by three frames, and so on.<br />When approaching stairs from the back (such as the staircase in stage 07-1), the timed up press saves either 1 or 2 frames on a 1-frame window, and being late still loses time. This is not recommended on these stairs.<br />It's also possible to achieve this time save with a jump that lands Simon perfectly below the stairs, and a buffered up press. It's important to note that the forward direction needs to also be addedheld on landing in order to not lose time.<br />This also works on stairs that go downward as well (such as the final staircase in stage 13).<br />Chained staircases (the ones in stage 07-2, stage 08-1 and stage 17-4) have some subtleties to them as well. Compared to purely holding up:*In stage 07-2, holding right+up loses 1 frame, while holding left+up saves 2 frames.*In stage 08-1, holding either right+up or left+up saves 2 frames.*in stage 17-4, holding left+up loses 1 frame, while holding right+up saves 2 frames.
