I think this game is more harder than portal2, or Q.U.B.E I only get green weapon .. and I don't know how to find all room, also I don't know where is yellow gun!!!!!! It is too hard game to me,, I think I have to watch Antlchamber Walktrhough on YOUTUBE, LOL:)
19.99$(22000 won) is pretty enough to pay to play this game. I like this game.
May be this writing have some(?) grammer error because english is not my mother language.

It's because there are speedruns that have been cutting close to 5 minutes. Average playtime for a new player, though is 4+ hours.

Just relax and take your time. There's no rush to finish. Go at your own pace. When your brain is sufficiently bent, you'll progress. :)

Having completely finished the game (found all pictures and rooms, restarted game and did a speedrun) and steam clocks me at having played it for 6 hours, I can see it as being a short game. but it is a good value, to me, for it's price. I have sunk less hours and gotten WAY less enjoyment out of game I have paid WAY more than 15 (or 20 at full price) bucks for than this game.

There was only a single puzzle I was unable to work out the room for on my own and I kicked myself for not trying it before (to be honest, it was fairly arbitrary, though).
