Thanks for the Reports! The Zombie horde is definitely missing a trigger there, i'll need to fix that!
And unlimited supply of med kits and energy drinks, gotta cut off that Sauce, lol.
yes i'm aware of a few walls that don't wish to retain solidity, trying to fix that up.
As for party members! the next update is switching things around with Karen taking makoto's place for a bit. I'm planning on reducing the infection attacks going forwards. soon you'll get Makoto and Karen and there are plans for 2 more party members.
The Highlighted Objects is more to alert you to a location of Interest rather then being the point of interest themselves. just to get you to notice save points or Entrances/exits. Might need to adjust them though if they aren't working as intended.
