Topic: Stuck on Level 36

In Chapter 36, in the castle levels, the checkpoint is set too far away to spam them. And you need to kill enemies to unlock the doors to the next hostage. There is a room that spawns in a bride at the top of the room, then three werewolves, before the walls open up revealing two mummies and a Frankenstein. This is where the issue arises. Because I cannot damage the Frankenstein using normal means, I cannot progress.

When I add multipliers and cheat per sey the doors wont open after killing Frankenstein
