That's okay. Thanks for trying them.

: Lijiang: people were kind of flummoxed by this; the flow seemed lacking, most
: of the weapons were loadout-tier, the verticality was weird

Maybe it works better with the ease of looking up and down on PC. When I did a small playtest (albeit only for a couple of rounds) people said the verticality was the big selling point. Oh well. It's pretty baked into the map concept so idk if there's much I can do about that.
I'll work on the flow - if there's any specific bits people wanted to call out, they're welcome to email/XBL message me.
The weapons being mostly silenced ARs/SMGs was intentional. It's a very tight map, so most power weapons would have been either pretty OP (shotguns, rockets, needlers, SAWs) or unwieldy (snipers). It might be possible to add in a couple more, if you feel that's necessary.

: Haunted Heart: too big, felt lacking, getting up on top of the ice wall is a
: bit OP, crouching in the bottom of the map to get to the teleporter and
: out of the map is very OP

Getting out of the map is definitely not working as intended. I'll take a look around and fix any places I find where you can do that.
Do you mind if I ask how many people you were playing it with? It is designed to be a fairly large Infection map, with room to maneuver for a full lobby. Could see about adding some more man cannons to make it feel smaller and more navigable, though.

Thanks again for testing, anyway.
