I killed the queen but lift door is still locked and I can't go to the exit. Maybe it is another bug or maybe I missed something.
I think that it is time to say "enough" and stop playing. Game can be hard but should be enjoyable too. Ecliptic is just hard. Player is overwhelmed by the number of enemies, weapons are weak, attacks are mostly missed, riddles are weird, there are red herrings (access card for room with nothing interesting inside).
