This is one of my favorite maps! You can quarter hack the laser in the "infinity laser" room then rush in to plant a C4. This eliminates the lasers and the laser door below it. Many different ways to solve things. Really makes you THINK rather than just rushing in.

I have updated the level. Changed mostly the underground and the second floor.

This is kinda discouraging :'( but I agree with most of your points. Though the underground safe with the lasers is not that mean imho, there are several solutions.

I didn't mean it's difficult for good players, but originally I meant it to be solvable for most people. (who are not complete beginners.) If I make another level it should be be good for stealth.

I gave up on special side views, because it's difficult to make for example a good looking statue on mere 8 floors.

...I forgot to say good things as well. It was a good map, not difficult like you said (though remaining unseen is basically impossible). Decorations were good, items were placed in areas where you wouldn't accidently pick them up. In general mobility around the map was also good.

Yay, more unique sideviews.
Difficultywise, the bottom floor and street level are way harder than the top floor. The reason for this is the lower two floors have fewer easily accessed LOS breaking areas (instead they have many bushes) while the top floor is completely made of them, making running away extremely easy.
The underground safe in the infinity laser room is a bit mean, and the street level safe doesnt appear to have enough computers to actually get it without triggering the lasers (not wrenching it).

The bottom room and the far right room on underground are far easier than they look, as triggering everything doesnt even cause many guards to see you.
Usually you dont want to have a laser right on top of or overlooking a vent entrance. :p
