Gameday feedback : played pyro and soldier
Sorry for being rude, but is this ant fortress ? The layout is somewhat really tricky. Of course there is a fair dose of sideways but I didn't enjoy much the experience :
The outdoors lacks some emptier space and somewhat felt too big, because of the many many curves one has to take to reach the goal. Take your middl spawn : you respawn, and you have to take a double stairs volley, then go along the glass sided corridor, etc. But then, there is an alternative...
Indoors, the mine. Corridor thin enough to let only one player + many dead ends = playing panic. What are : scouts/pyros/spies supposed to exactly do in those underground tunnels ?
Worse, the constant and brutal changing of direction + changing of vertical level destroy every tiny bit of "smoothness" in the gameplay. You did use sign but once you've fought under there, you can be totally lost about where you're facing and what you're supposed to do.
So what should be done : enlarge your underground area to let every tiny bit (exept dead ends) to be at least twice or thrice the player size. Remove/smoothen/simplify some map transitions, players may want to go through "S" or "N" shaped passages, but "W" or more are a no go. On outdoors, give a bit more room for players to "breath". Add signs, signs signs and detail your underground zone to give navigation hints : One wants to know where he is just by looking at his surroundings.
Good luck
