Thanks for playing.
1. I can't reproduce the crash with the skull door. If you can record this, please send me a video.
2. Were the blood splatters white, or were they a different texture altogether? I've noticed decals occasionally switch to a different type, but never just color.
I just removed the "inspecting" plasma rifle animation - I personally found it too obscuring as well. It won't be seen in the next demo day.
The mouse sensitivity issue indicates that FPS is a factor, since I think the Vulkan renderer has a higher performance. I'll try to fix the root cause, but if I can't, maybe I'll just raise the limit that users can set to sensitivity in the options menu sliders.
Movement/collision code definitely needs work. I'll try to spend a dedicated block of time of fixing them.
