A short, challenging map using gravity flips. It's sort of glitchy in some areas, (not much I can do about it,) but I worked hard on making this map look professional, and I think it's my best so far. Enjoy, and please comment on what I can do to make my maps better!

1.1.1

Made into a vpk file so my custom sign works!

1.1.0

Made 'lower' chamber have a metal floor to prevent an unintended, very fast solution. Added white wall to allow player to return to 'top' chamber.

1.0.0

Short map in Clean based on worldportals: despite the flawless looks, I found it confusing due to one macroscopic flaw. And consider that I love this subgenre of mindgames such as The halls of Menoetius Co-op or sp_tod_Sprunrun

On to the problem, imagine two rooms connected by a vertical tunnel where gravity turns upside\down. Only this "inversion" is lopsided: fall from one side and you'll fling 3 meters, fling from the other and it will be 10. It's unintuitive when dealing with item physics: they react inconsistently, imho that should be reworked. I tried taming the physics until I thought I had a sure grasp of the solution, then just got my mind on breaking through and got out.

Bugs: the bridge area seems to scramble the cube, which dances around; the convenient white wall in the pit is supposed to prevent you from getting stuck, but get taken in between the 2 worlds and you'll still risk to vomit (already happened with Thinking With Gravity ).

Wow! I actually never thought to solve it that way. What I did was slightly differant in the first part. I used the 2 white walls in the 'top' room I provided to get the laser set up, portal down to the chamber 'below' and on my way up put the portal back in its place, then 'fall' back 'down' to the 'lower' chamber. Kind of hard to explain without video capture software. Oh well.

Thanks for your comment! Yeah, the white wall is there to prevent getting stuck. The gravity shift was uneven, but if I changed it I would have to rework some of the puzzle to make the velocities and stuff work out. And the cube spazzing was wierd aswell. Don't know how to fix it though.

Anyhow, thanks again for commenting! I'm glad you liked my map! (And that it has flawless looks!)

By the way, did you examine the observation room in the 'lower' chamber?

The one upside down? I didn't try to get in, there's easter eggs?

Just looks like table and chairs are up.

Nice map, liked it.
I also tried to rotate the reflective cube to point downwards to solve it and almost got angry because it was quite hard to turn it and point straight down. I tried for a while until i realized the intended solution. I like how subtile it is.

Getting 'stuck' between the 2 gravity areas is a bit annoying when the mouse starts acting weird and the camera switches all the time but i guess there's nothing you can do about it, mayb areal faith plates with max speed parameters, dunno.

Nope, you can't get in. Just a little easter egg with an upside down observation room, making it look like the chamber was gravity-flipped but the rest of the enrichment center is right side up.

Due to the nature of linked_portal_doors, the 'getting stuck' is kind of unavoidable. There's a white wall there if you do get stuck, but theres not much I can do about the camera/mouse spazzing.

Anyhow, I'm glad you enjoyed it!

Nice good looking map
but i'm not sure that i solved puzzle as it was intended

Haha, no u didn't!

You should try to solve it the intended way, it's a good test.

Good thing this can easily be fixed by making the floor of the lower level unportable.

Yep, that was an unintended way... I cant JUST make floor not portable, that would screw it up. I'll work on it. Thanks for pointing that out!

EDIT: Updated the map. Made 'lower' chamber have metal floor and added white wall so player can still come back up without catapult, but be unable to bypass most of the puzzle.

Played Ver 1.0.0. - the 'as intended' solution. Great map, the time for execution of the last phase to the exit was reasonably generous - thank you....
thanks for creating - looking forward to your next....

Thanks! There was 30 seconds on the two buttons if I recall correctly. When I tested the chamber, (countless times,) it only gave me a little while to spare. I didn't want it to be too easy, but I wanted to allow room for making a little mistake with portal placement or something and not have to start over. Glad you enjoyed it! My next map will probably also have gravity flips, only on a larger scale....

Can't seem to solve this. Are there ninja skills involved?

There's video walkthroughs and instructions from the mapper himself in the previous posts.

There are 2 solutions I know of, (both similar in their final part.) Ninja skills are not needed. For one solution it takes a little 'portalling while flying', but you have a second or two window, so its not ninja by a long shot.

If you're really stuck, watch the video walkthrough, (not the cheat; I fixed that and updated the map anyway.) But I suggest just looking and seeing what activates what, thinking about everything you have to do, and as always, think with portals!

What a great map. I did it the intended way I believe - but got stuck for quite some time figuring it out. I had actually tried the tricky way of aiming the laser cube down but it would not rotate when I stepped on it and slowly moved back - maybe you made that impossible sommehow since.

Thanks for this - I really enjoyed it.

I solved it the way xdiesp did, by pointing the cube down, but with an even shorter route to the cube button, and even then, I just made it. I also had a problem with how the cube behaved around the hole. I dropped the cube to put the portal in the cube button room, and the cube got sucked into the hole. The biggest time killer for me was the narrow gap to the cube button, although I guess there were other ways to get in there. This map got my blood pressure up, and I'm docking it one point for tight timing. But conceptually, this was an excellent map. While the glitches were obvious, they didn't actually impeded the solution. So I give it 4/5.
