A classic horror premise and setting, executed solidly to a TKG standard - proposed alternative title: Would you still love me (if I was worms)
+ Lots of NPCs to utilize with a good mix of infected and non infected people for a slow burn to unveil the chaos
+ Great timeline table to keep the game going in an eerie way only possible in a hospital
+ Good amount of details about how the worms behave, giving enough inspiration to build on them.
If you're looking for feedback, let me know and I'll expand further.
