Love the premise and the oppressive atmosphere, though I have to say it gets quite tedious having to redo the first few levels every time you die. I know that's part of the point and setting, but from a gameplay standpoint, I think a shortcut every few levels that you can unlock for future runs would make the trial/error aspect a whole lot more bearable, especially if you're going to have instant kills like the trapdoor spider alien and the vines (at least, I think the vines are instant kill). I don't think I saw any hint of the vine either, which made it extra unfair imo. On a side note, you seem to have "always run" on by default, which is probably a result of your config.save being uploaded alongside the project. Since stamina is an important resource, I think it should be something that players can more easily control instead of having to hold down shift to walk. All in all, good work still!
