Not a bad game but constantly spamming X to try to defrost the Frozen Guy once was enough to drive up a wall. Doing it again because the second key cannot be found anywhere is driving me positively spare.
Not bad. Personally, I'm glad that the rescues don't follow you around like ducklings when you save them. That would add a whole other level of difficulty. "NO! Don't walk into that bullet! You idiot! AH! Now I have to start all over again..."
[Observation]: Yellow-haired humans run away when the lights are switched off. The yellow-capped humans can turn them back on.
[Suggestion]: Simultaneously hack all the robots on the same floor when all the yellow-capped humans congregate together.
