Thank you kindly for your comment! I'm relieved that you didn't find it nauseating to play. That was one of my worries since a low framerate can compound the experience, so I agree that there could be some quality of life improvements on this game.
The rest of your comment was kind of funny to me (besides the clever ceasar encryption), because there actually is a gun somewhere in the ship (it spawns inside one of the three decks), though it can be hard to find due to how disorienting the game can be. The gun is not necessary to complete the game, but it can be helpful. I would not dare lie to the player and tell them about a non existent gun xD even if that could be a good idea, if executed properly.
This just shows that I did not a good job at properly guiding the player toward a clear goal, although it does not seem like a problem for seasoned players like yourself.
Anyway, I'm very happy that you could finish the game and had fun playing it!
