The asynchronous animation is kinda weird, yeah, but it's a lot better than the first draft, which was pretty much always the result happening, recording, and appearing before the action. Personally I like the new style better just because things can play out a lot faster than they used to (such as Arachnotrons firing all at the same time) and the animation after/during the calculation is something you get used to. It's "buggy" in a visual sense but it's running as intended right now: if Kornel thinks he can improve on the engine, that's probably another big project.
It's pretty awkward when you die before you hear the bullet that killed you, though. (Basically you hear the projectile just as the mortem comes into view. Given the unique nature of death, this case might be "fixable" if you wanted to try.)
