yep. saving in general doesn't seem to work for me. pressing enter just adds a new character. i can remove him again by holding escape thoug, but the save symbol at the top just never disappears.
not being able to go into any quest-related building is really a bummer for me.
even with the highest tier of base i somehow still feel rushed to go into the city, do things as fast as possible and then return to base. what if i just want to take a stroll? :D (or try to find any other characters besides lady with gun at the left and police girl shouting "find my friend" then dying to a zomzom).
the idea of having to find characters for towers is nice, but you have a hard time finding those characters. they're more like colectables, and with a constant horde approaching, you don't really have time to spend half an hour exploring a part of the city.
the traps and spike ideas are nice, but having to constantly replace them doesn't seem to be worth the hassle.
the walls repairing themselves after each horde is nice, but i still have no clue when they break. do i have to rush to the wall and smash the zombies there, before they tear it down, or can i take my time, lure a bunch of zombies into my traps, while the other zombies peacefully enjoy their wall-meal? a health bar would be nice to have, especially since the wall already has a hidden "durability"-stat. no point in hiding the condition of a wall, if it has a condition.
online multiplayer AFTER ps4 release? sure, i can understand that you want to make a couch coop game, but on the pc, there isn't really a market for such a niche genre. take a look at overcooked for example: fantastic game, if you have friends sitting next to you. everyone is asking for online multiplayer, because their friends are sitting on the other side of the world. online multiplayer would boost the popularity of the game massively, and waiting for it after ps4-release might be hard, as such late in development, adding online functionalities surely becomes a hassle, as everything in the game has to be changed around for it to work with the multiplayer scripts. either you add it now or never.
but yeah, apart from not being able to advance (or save, even though i started the program as administrator and such), the game is still fun, but because of the aforementioned issues, it quickly loses it's appeal. maybe if i would be able to convince a friend to play with me... oh, wait. doesn#t matter anyways :D
