I'm of the opinion that, among many indie game puzzle platformers, the "platformer" part really doesn't add very much to the "puzzle" part, especially ones which are clearly imitative of Portal. While Portal was ostensibly a "3D platformer", that doesn't necessarily mean that its puzzles or puzzle design clarity naturally degrades down to a 2D platformer. Too much focus is given on the length-height plane of Portal's puzzles, and, I feel, not enough on the length-width plane. So, in that vein, here are the first two levels of a game that is not a puzzle platformer.

WASD - Move.
Mouse - Aim.
Left click - Teleport.
R - Restart.
Reach the staircase to escape.

As it turns out it took ages to implement the special blocks' mechanics, so you only get 2 levels for now. Maybe in the future more will come forth.

The main inspiration for this was probably Epsilon, a somewhat drearily-coloured Portal-inspired puzzle game that is, strictly speaking, not a platformer either.

(Note: This may seem like I'm especially talking about the recent indie release "Gateways" but I haven't actually played that game outside of the first minute of the demo.)

This is just a single difficult puzzle similar to the sort you might find in Karoshi 2.0 or The Impossible Quiz. You must "think outside the box" and come up with a very specific solution to this seemingly impossible task of your own accord. I will reveal the solution in a day or two.

Note: there might be a bug that causes it to be solved immediately. Please disregard this if it occurs.
