I tested the map and I found a lot of issues, some smalls and other very big ones:
The light of the cart is always active (check my gamemode prefab, i think it's fixed there)
There is a player clip here for no reason, so you can't reach the wall and its just odd
Same here, add a spawn visualizer for all teams so it's clear you can't go in (same in BLU side)
Also z-fighting in these rails
It's a winter map, but the calendar says its June... I mean, it's possible if this map takes place in the lower half of the world i guess
This area just feels empty, add some props around it
This ray light is too small (in the same area)
This door near BLU doesn't reach the floor, making a weird black bar
Also in the same area, this dumpster is floating
There is some textures that doesnt fit TF2 at all, these are probably the most obvious ones
All the packs have this roof thing underneath them, and i'm not sure why, i could understand if it was over snow or something, but its everywhere and im sure patches would work a lot better
Also you forgot to add a patch in the middle one
There is something weird with some doors, specially this one, where the outside looks broken, no idea why, maybe you have multiple areaportals?
Same thing happens from the other side
When you start drowning underwater, the effect texture seems to be broken, making it impossible to see underwater
This area seems out of bound, but you can actually get inside, not sure if its intencional or not
Same deal in BLU side
Little issue with the overlays here
Dev texture here, also that door is just a metal wall, it doesnt look like a door at all and it would be impossible to open, you can use instead a wood door model instead
Basically like you did here, also disable the collision of this door
You forgot to add a menu photo (just use my prefab, it will take you a few minutes only)
At last the mode uses a custom text for the objective so check the original custom files for that (also i did the translation to spanish of that text too)
