Difficulty: Medium

Welcome to Contrapositive! This puzzle features a funnel, piston platform, and a couple of cubes. All portal surfaces in this map are on the ceiling, so be sure to focus your attention upwards. Though it can feel a bit clunky to play sometimes, I feel that I achieved what I set out to do and more when I started designing this one. I am quite happy with the sequence, as I hope you'll be when you figure it out.

As usual, no cube throws, tight timings, or fancy maneuvers are required to solve the puzzle, only brains.

This map was made as an entry to a contest held by klaus.sfc01. The theme of the competition was to only have portal surfaces on the ceiling, which turned out to be quite a restriction. Fortunately, however, having a restriction like this in place can sometimes facilitate the arrival at a complete puzzle faster.

Some things to note:
- It is not intended nor helpful to push a cube through any grating
- Pushing the player through grating will turn the player into spaghetti (death)
- It is not intended nor helpful for the player to push themselves against the flow of the funnel
- Ignore the flashing lights on the faith plates; they will still work normally

@Mattchew that's pretty high praise. You sure you just haven't gotten to the good workshop maps yet?

Even after a couple of weeks, it is hard to put into words how much I love this map. New personal favorite!

Hard work! ^^ I was clueless for quite some time and felt heavily restricted. After all the ghost maneuvers that popped into my mind little by little, reaching the exit felt so rewarding :-)
The null portal move was also very clever. After it happened by accident it took a few more minutes for me to see that it was actually helpful ^^
Agree with Narkodes about the grated panels being too dark, though I see your hint in the design (panels being carved out and with white edges and lightstrips).
Didn't experience Nobody's and Mikeastro's confusion with the exit surface. Imo it's clear that pushing and/or pulling a cube here makes no sense.
The final two sacrifice timings were pretty tight (yet feasible). Let's say there was no risk either since you can rebuild the setting easily.

Tricky one! Glad I figured it out, had me puzzled for a long while

Very nice cube stack puzzle! I like how you worked in that it has to be done multiple times.

Very nice map. I experienced the same confusion as @Nobody No-One. Big thumbs up :D

Really nice map with a remarkably elegant setup, and I always love a good ghost cube maneuver. My only criticism is that the grated surface you use to get to the exit is a little bit of a red herring, since the fact that it's directly above a button is, as far as I can tell, not relevant to the puzzle. Big thumbs up.
