Unholy Realms - Map 20 - Rite of Passage... need help

Hi all. After I get the blue key card and activate the switch, the wall opens up with all the cacodemons, etc. When I go to the teleporter to get the red key, it transports me, but I get immobilized and end up dieing every time. It won't let me run down the walkway to get the red key. Is this a glitch or did I miss something? Thanks

Maybe this may help you.

Could be an issued with the incredibly hacked voodoo doll effect. Could also be a problem with the 8-bit platform in the blood pool. Either or.

No one else has reported an issue with this - what source port and do you have a demo/footage?
