Awesome. The sense of dread and claustrophobia from your scent being a lure for enemies is really effective.
I did notice that the stairs between levels 0 and 1 do not seem to be properly connected, but that's the only glitch I found.
Suggestions:
- It would be nice to add some clues as to what happened to the other passengers that you can find along the way, or other effects that can build on the theme, like finding bodies or blood or encountering other survivors.
- What if they can sense your smell, but you can hear them? Close a door and listen at it, and you can tell where the zombies are shuffling by. Maybe have other sound effects that you hear throughout the ship, like rustlings, bangings, screams.
- I like that the passenger rooms are varied, but it does get a little tedious to search them all for painkillers. Maybe reduce the number of them, or put some non-passenger rooms in there to break it up a bit, with interactable elements in them.
- It would be nice to have clever opportunities to mask your scent somehow, or create distractions for the zombies.
- Maybe have more zombies, but they move more slowly so you can actually outrun them?
Anyway, great work. Really strong theme from this one!
