1. Pretty self-explanatory.

2. The top box (that I'm pointing at at the start) should be moved a bit to the right to make it possible for a CT sniper to climb on top of them. This would make the role of a CT sniper on the A site a bit more interesting, as the CT sniper has the opportunity to come from more than one angle to peek the A site/opposing sniper.

3. Barrels are acting funky.

4. Imho there needs to be a ladder to the second floor here. Imagine being the last CT trying to defuse the bomb and the last T is in one of the rooms on the second floor, waiting to kill you while you're defusing. This situation happens all the time but on most maps you have a chance to chase and kill the last T before the time runs out. This is practically impossible here, as you would have to take a huge detour to reach the second floor. Probably not enough to make it back in time to defuse the bomb. I don't know how much testing you've done with people, but there might be a really good reason there isn't a ladder here. My train of thought might be totally wrong on this one but it's just what I'm feeling ;D
