Ok, more useful upgrade comes :3
1) Zombie behavior changed, so they don’t chase user while “see” them, they chase even after they loose them by going to last point, where they see him;
2) Added inventory & some items
2.1) Keycards to open different type (color) doors (8 types of doors, 8 cards)
2.2) Boots (can be founded on 4-th level in first big building at left). They make player to accelerate & move faster;
2.3) GraviBall (on 3-rd level of first big building, left). Its allowing of doublejump.
2.4) Silencer (On 2-nd level room, after green door, green key is on rigth after top floor of building). Makes shoots quetly a bit.
3) Shoots attracts zombies. Without silencer zombie in area of 1024 pixels “hear” shhots & come to check “what is going on?”. With silencer area is 128 pixels.
4) Doors & keydoors (locked). Opens for few seconds, then close. Locked (colored) requires keycards of same color.
5) To exit level 1 you need a black keycard (on left balcony, almost top floor), and this card is single-use (final door “eats” keycard);
6) Animation. Added jump & fall singleframe animations :)

Testing still preceed, but game slowly gets playable.

Now its honest EGA simulation (before this zombies, day sky & hearts was not 16 colors)
CRT effect (planning add opinion to set parameters/turn off in future planned options menu)
Level 2 (same as level 1 with no first building – the big one, player spawn room still stay)
Sky no more Altha 16/32 bpp, now its dotted some-kind-of-Alpha honest 4bit EGA.
