Ok guys. I installed demo version and comparised behavior with new build.
1. Fire is the same. I apologize about it. But I just don't like current effect (it's my personal problem)
2. First problem is that walls and other stuff damage behavior is broken. Walls just disappear without breaking stadies.
3. After staff is destroyed there are purple artefacts on the screen where destroyed object was previously. It reproduces with walls, mars machine.
4. Alliens became very accurate. 99% shots goes to target. Maybe it's not a problem.
That;s all for now.
