Solved in 2-3 minutes. It really isn't very difficult, especially considering my slow thoughtful approach.

(Dedicated to wildgoosespeeder) If you liked the map, you should also try some of my others. I recommend "GLaDOS Wakes: Chapter 1", which involves a new puzzle element, or some of my other "Quest for Cake" test chambers.

@Malfaction: the portal number counts ALL portals you shoot, so shooting a blue and an orange portal counts as shooting 2 portals.

I Win !!! Used only ONE portal while blindfolded with both hands tied behind my back !!

I finished it! It was really good!

This map I found to be a pretty good Portal 1 test. It isn't that hard as you made it out to be. I couldn't break or exploit it, as far as I could tell. Consider this a personal milestone of yours in test chamber creation. Is it a true show of what kind of potential you have? Maybe. Just keep playing and creating the occasional test from your play sessions. Hope to see good maps come from you soon. I did it in 2 portals in probably 2 minutes (wasn't keeping track)! :D

2 is all that's necessary, if you know ahead of time you're supposed to try for 2. Otherwise, probably 3-4 including adjusting the height of one of them.

I got a silver ... I think; maybe a gold; depends on how you count the in/out portal pairs. Thumbs up!

In case you want an additional challenge, here are the lowest portal amounts.
Bronze = 5; Silver = 3; Gold = 2.
