This is pretty good game, but music and sound effects would make it much, much better. Try AlienRL and you’ll see what I mean. Kind of atmosphere from Doom or Quake, tense… so tense you jump out of your seat when you suddenly hear zombie breathing down on your neck.
Colors are too dark in this version. Day looks like night now, I can barely see where the doors are, and dark gray text is far more unreadable, it’s almost invisible.
Screen is too long horizontally, which is problem as it sets unnecessary limit to enlarge font/screen size. Top right part is unnecessary, rather use mini-map to show some approximate position of monsters there, and possibly make mini-map bigger. Bottom right part can also be shrunk considerably.
I’d prefer all the menus could be navigated with arrow keys.
Wear and take off clothes should be multi-choice selection like drop command is.
I think vehicles should turn in 45 degrees steps.
And have I mentioned music and sound effects? It would make so much difference.
