Be sure to make use of the 'tab' function in which you can see what your partner sees. Keep in mind in cooperative chambers you must employ two sets of portals. Teamwork and communication is key to completing any cooperative test chamber.

Nice level. There seems to be an issue with the orange goo. For the player on the left side, I could only place the portal under the goo by standing in the inside. It would be helpful if the respawn from that area was in that area so that one player doesn't have to commit suicide to let the other in.

Cool map. Check mine out at http://steamcommunity.com/sharedfiles/filedetails/?id=364674434
It's the first one I've made. You need two people in order to beat it, and I would rate it as a really good challenge for all levels of players.

Your chamber is prone to " portal bumping ".

nice map, only thing is, we parked the companion cube on the upper floor and fell down. Companioncube stayed on the upper floor and we couldnt spawn a new one to get back up there
