Description
A collection of custom cooperative test chambers made by SunnyOst.
Made exclusively mostly with PeTI editor, some with extended item limit.
Wide range of difficulty(Easy/Medium/Hard*. Pretty wide, eh? #livingtothefullest).
For more info about maps, read the description for each map.
Some of the maps in this list have stereoscopic 3D screenshots(WOW!!!), You might want to check them out aswell.

Update: Harder/more annoying maps are now at the end**, to keep people playing for longer! :D

*IMO EZ/EZ/EZ nah mean #MLG #1337
**Except for the first two.

TOO CO-OPERATIVE? TRY THESE: https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=642194058

Destroy Them, My Robots! (CO-OP)
Created by SunnyOst
A concept-proof map, showcasing the 'destroyed cube switch'. For map-makers mostly, though it might be a bit hard. In singleplayer it is harder to destroy cubes, apparently, so co-op is a preferred type of map for this. Made with PeTI Editor with extended ...
Don't Look Down (CO-OP)
Created by SunnyOst
This chamber is a little experiment with a glitch I found. Take a cube, look down and... Enjoy! :> --------------------------------------------- Glitch info: Reflector cubes stop player movement if conditions are met. Conditions are: -Reflector has been in...
Donuts (Co-Op)
Created by SunnyOst
Someone asked me to make one. WARNING! Extremely easy! There's only enough magic for one player at a time - I'm a beginner magician, sorry ...
SunnyCo-op: Warm-Up
Created by SunnyOst
First Co-op map. Easy difficulty level. A bit of thinking required though :D Enjoy!...
SunnyCo-op: Jeffrey
Created by SunnyOst
Fifth Co-op Chamber. Made with PeTI Editor. Easy difficulty level. Enjoy! :) ---------------------------------------------- Not really much puzzle here, because it was made exclusively for this hint: Hopefully You've seen "Get Him to the Greek" ♪♬ When the...
SunnyCo-op: That must have been one Hell of an Easter Bunny
Created by SunnyOst
Fourth Co-op Chamber. Part of this puzzle is based on a dream I had recently(everything before the double laser). Made primarily for dream reference and an Easter Egg. Made with PeTI, with extended item limit. Easy-Medium difficulty. Enjoy! :) ------------...
SunnyCo-op: Coffee Spill
Created by SunnyOst
Saw this chamber in a dream. Medium difficulty. Enjoy! :) Check out other versions too: Coffee Lake Bigger Spill v1.1 Updated design. Removed the "hold-the-cube" solution, in favor of a prettier one. Removed the "place-the-cube-by-the-button-but-not-on-the...
SunnyCo-op: Mixed Feelings
Created by SunnyOst
Another chamber I saw in a dream. Parts of this chamber are Hard, others are Easy, nature of the puzzles varies too, hence the name. Hard parts can actually be finished by a single person, but it's hard to judge which way is easier. No strafing or speedrun...
Coffee Lake (Co-op)
Created by SunnyOst
Another go at ruining this puzzle and enjoyment of the game for others. Tested and certified finishable. Check out other versions too: Coffee Spill Bigger Spill v1.1 Removed forced solution and updated visibility a bit, since it's getting kind of popular...
SunnyCo-op: Bigger Spill
Created by SunnyOst
Saw this chamber in a dream. Less easy version. Enjoy! :) Check out other versions too: Coffee Spill Coffee Lake Updates: v1.1 Updated design...
[Co-Op]Send Nudes
Created by SunnyOst
This is a legit map with an actual puzzle, I promise. So I wanted to use this one trick*, and just made this little thingy. Decided to go with "default room" style, but might have changed it a tad too much. In case you actually decide to send nudes, pm me ...
SunnyCo-op: Cathedral
Created by SunnyOst
Third Co-op map. Big. Made with PeTI, with extended item limit. Tested, finished by several people in different ways. Might be glitchy or laggy, didn't stop me. Hard(for average players) and time consuming(for everyone). Enjoy! :) To save everyone a bit of...
SunnyCo-op: The Bad One
Created by SunnyOst
Formerly known as Time Code. This map was an early experiment with PeTI based custom timers. Unfortunately it is full of exploits and weird parts(like going into angled panel at an angle, which doesn't work all that great, or a very tight timing on a part ...
SunnyCo-op: Small Intestine
Created by SunnyOst
WARNING Watch Your step! Or you'll get very annoyed very fast. This the only decent part of my other silly map "Party Pooper". There it played a role of a small intestine, hence the name. Enjoy! :)...
easy dream CO-Op
Created by SunnyOst
Just another map I saw in a dream. The first room is remade pretty much 1 to 1, but from the second room I only remebered the trick used, so improvised everything else. No crazy timing/jumping/whatever necessary and absolutely possible. Square buttons are ...
HELLocity
Created by SunnyOst
For all the Gelocity fans <3 When you get to the exit door, it gets better! (not just because you are finally leaving) Might not work correctly with controllers! Second checkpoint is a bit buggy, so try not to die on the tube :D If you liked this map, you'...
Maynard: Portal Stories Co-Op
Created by SunnyOst
Works much better in local Co-Op! Use Remote Play or whatever! Some say "three's a company", I say "third time's the charm". Meet Maynard. Maynard has more brains than both of you and for the most part they are spread out unevenly between you too! Wheels g...
