Testing focus: Lasers and Hazardous Liquids
Difficulty: Easy-medium / medium
Expected play time: Several minutes to, say, twenty?
Version: 1.1

This map features Thermal Discouragement Beams, Toxic Goo and Fizzlers, with some Laser Redirection required. It doesn't focus on laser relays though, it actually revolves more around logic. No quick finger needed, just logic.

The name of the map, Prolonged Exposure, refers to both the use of lasers and the deterioration of these otherwise pristine test chambers. The artstyle of the map is the same as of the Penrose Collection but this time around the walls are going to be opened up a little to reveal the underlying rock.

The map was originally supposed to enter in the Heavy-Duty Super-Mapping Super-Contest on ThinkingWithPortals, but under the circumstances I couln't upload it in time. So here it is now, I hope you'll like it. If you do, I reccomend you subscribe to me for more maps. :D

PS: I hope you'll forgive me for taking a break from the Penrose Collection for this one.

The thread for the map on ThinkinWithPortals can be found here:


Version 1.1
- Added autosaves.
- Fixed some indicator lines and other details.
- Made the dried up goopit less deadly. (Still deadly though.)
- [Possibly] fixed my custom cube skins not showing up properly.

I added your map to my new Anthology of community-made gems (an ongoing WIP). You can see it here: http://steamcommunity.com/sharedfiles/filedetails/?id=192138122. Thank you for making this map!

Great customised elements as well as a fun to play set of puzzles. Will rate it at TWP -Thunbs up 5/5! Thanks for mapping!

Fun map. Enjoyed it. Challenging without being frustrating.

The one problem I had with it was the mine area room. Maybe because it's late I did not see the space that allowed the portal to the lazer cube room. Given there are large piston like objects in the way and signage pointing forwards, initially I thought I would have to do something to move the entire wall. Making that surface glass would go a long way in helping the player see what is going on. Visual difficulty isn't mental difficulty.

My newest: Mouse Eats Cat </3

My hardest: Major Lazer - Will Melt Your Brain

Made my Favorites list! Fantastic! Hard, but not mind-meltingly insane like a good Mevious map!

Huh. Well I think I get what you mean if you used the slanted platform there but.. that would have indeed been a lot trickier. Congrats on getting to the exit though, hope you still liked it.

I watched his video. My solution was almost the same. Only at the end was really different. I used that pit as part of my solution. Made it harder,

Ooh, now I'm curious. Mevious made a video with the intended solutions down below in the comments, so if you want you could check if you did it differently. ;)
