Hi! What happened when you experienced a bug trying to enter the password? Could you describe the bug?
Footsteps' sound is actually loud, I agree. We are working on the next portion of minor bugfixes where we'll lower it.
In terms of the story, we tried to make it like a generic hollywood movie intentionally. So, no wonder the story felt cliche :)
Speaking of the endings, the one where you need to find 4 codes to open a sarcophagus (cargo) is the most difficult. It takes 2 short quests to find missing pieces of code. One quest is to fix the wire at the Cargo Bay, and another is to check the ventilation with the drone at the Engineering Deck. The ending you are describing is the shortest,if I'm not mistaken as there are two computers which lead to endings. One computer asks you whether you want to escape or stay on the ship. Another terminal offers a variation of two endings for you to decide. So there is always a choice:)
