I'm trying to go through all of the marathon stages, but my character keeps freezing. I died once and when I respawned, the model didn't seem to update, leaving me to slide around in a default pose. The model breifly changed during climbing, landing, and swinging, but only by one frame. After a while, and a few more deaths, I appear to be stuck in place. I can still move the camera with my mouse, but the keyboard controls won't work except for esc. It might just be my computer, but I'd appreciate it if you looked into it regardless.
