Thanks for the feedback, everybody! I hoped that the next update will have a new map, but it's still far from completion, so:
Public Test 1.2:
DECORATE:
Added: mummies can now resurrect fallen mummies (just like in the original version).
Added FORCEXYBILLBOARD flag to all projectiles.
Added: player now has "usefail" sound.
Anubis Zombie: changed projectile damage (1 -> (random(12, 16))).
Anubis Zombie: changed PainChance (100 -> 80).
Mummy: changed projectile damage (5 -> (random(15, 20))).
Mummy: changed projectile speed (4 -> 8).
Mummy: increased projectile acceleration (1.03 -> 1.08).
Spider: slightly increased movement speed (3 -> 3.2).
Magnum: changed the maximum ammo ammount to match the original version (99 -> 300).
M-60: changed the maximum ammo ammount to match the original version (200 -> 300).
Grenades can now be thrown underwater (hotkey only).
Fixed: Blocking Decorations could be moved by projectiles and explosions.
Fixed: When player stood on a thing, his sprite was stuck in "jumping" mode.
Fixed: lowered falling damage recieved by player (1.0 -> 0.6), so it works more like in the original version.
Cosmetic decorate changes here and there to make stuff look a bit more random.
...And more small tweaks I've forgot about.
ACS:
Added Serious Sam-style underwater camera swaying (see qtilt.acs).
MAPS:
Fixed NODES error in MAP01.
Cosmetic changes in MAP01.
MISC:
Changed status bar type from Fullscreen to Normal.
Replaced some sounds which had cracking noises with better recoded ones.
