This is it. My 40th test chamber. And it's one of my best yet.

This challenging brain-teaser is almost certainly my hardest one ever: you'll have to use all the wit and intelligence you can muster in order to complete it.

Estimated difficulty: Advanced

Created by Demon Arisen
Switch seamlessly between a light bridge and a funnel with just the flick of a switch. Well... With the deactivation of a laser node. But that doesn't sound as catchy.

So yeah, this one isn't too hard. But it uses an interesting mechanic and I hope it's...

EDIT 1: Refined the test by removing angled panel and portalable floor, checked for exploits and trapping issues.

EDIT 2: Removed some portalable surfaces to prevent exploits

Order is everything. Only by placing the right portals in the right places ...

Pure Logic

Finally! A new chamber! It's been a while, hasn't it?

Of course I won't provide a description for my creation, what are you talking about?

.....and yet so far.

The exit is right in front of you, but you may need just that little extra blob of gel to reach it. It's bouncy puzzle-solving fun for the whole family! Okay, maybe not the whole family.

Excursion Conundrum

Indirect Redux

A remake of one of my best chambers (Indirect), Indirect Redux is a head-scratching puzzle which looks extremely simple - but it isn't.

So what's changed from the original?

Just a little chamber, because a little chamber is better than no chamber at all.

EDIT 1: Completely removed the two normal cubes, the flip panel, and the button which activates it, since none of them were required to solve the test (whoops) . Also made lots of visual tweaks.

Difficulty: Medium

(3x3x3) Nudge.
Created by Demon Arisen
Just a tiny test because I had this idea to do with using a light bridge in a clever way. A proper chamber should be out soon, but you can play this in the meantime. Aren't you lucky? Yes you are.

Estimated playtime: <5 mins, probably.

EDIT 1: Neither the cube nor the player should be able to become trapped. Moved the laserfield and added a respawn button for the cube.

This may just be one of my best tests yet.
