Just some technical problems I've found after playing this for a while:

1. Buyzone in T Spawn doesn't always work for all spawn positions.
2. The crates rack in B Site has no clipping on grenades (hence grenades going 'through' it)
3. The crates rack(s) in Long A also have no clipping on grenades.

Some other stuff I wanted say to better the gameplay competitively on this map:

1. Get rid of the ladder section from Connector to Office.
-- I say this because this section is EXTREMELY easy for CTs to rush to and gain not only the upper windows, but also guard the stairs section towards Radio, which is the only other route for Ts to use if they want to go A, besides the Long A route. Having that vantage point from the windows available to CTs from the start will make it much harder for Ts to rush in and take Site A, as there is already more camping spots on A than there is B. Removing this section would also make Mid a much more valuable section to control on the map at the start, since the only way the CTs will have a chance at stopping a rush from Radio from the start would be rushing the ladder in Mid. This is generally a pretty small map, so fast starts are to be expected.

2. Remove the connecting section of Tunnels to Mid.
-- To be honest, it's probably the most pointless route in the map. If CTs are rushing Mid, that would be the only route they could rush, since they would already have control of the connector/ladder area from Site A. The only problem with rushing that is if the Ts rush from their spawn towards Tunnel Stairs, they could immediately stop any kind of rush from CTs, not to mention the openable sliding door that completely exposes the whole section, with only some cover in the back. While it might make if faster to rotate from A to B towards Rafters, the middle walkway and a rotation through CT Spawn are faster, and also generally safer ways to rotate through.

3. Cover up opening on Bridge (middle walkway).
-- I'll try to explain this as best as I can, but there is a HUGE issue with part of the middle walkway that makes a T push from Office to B Site nearly impossible. In between the wall of the B building and the blue container is a small opening. This WILL be a huge advatange for the CTs, as 1 of them (with an AWP) could camp inside of Garage and halt just about any attempt to enter B Site from the walkway. Having said this, Ts will then have only 1 real way to enter into the site from their spawn and will make it that much harder to take over. The camping spot in Garage also has cover to hide behind as well (ramp barrier), which makes the camper even harder to try and kill.

Besides the map being slightly unoptimized, it's very CT sided at the moment. CTs can control a large portion of the map right at the start, so giving the CTs less routes to take at the start would be the only real way to fix this. This is a pretty small sized map, so fast games are to be expected, but will get held up by the lack of routes that the Ts have at their disposal.

Visuals looks great, and I can tell that this was thought out in a way. Really like the idea of the windows being breakable for flashbang entrances! Other than that, I can't really say much else.

Keep up the good work!
