I restarted the tutorial a few times, but I was not able to reproduce the problem. Seems not to be a serious issue.
Another thing is: I do not really understand why I need a fire? The tutorial tells it helps to see enemies, but the night is not very dark. My impression was, that defenses also work without fires. Maybe make the night darker? Make it more "spooky" when there are no fires?
If you have time you could take a look at https://crashdumpsoftware.itch.io/crits it is a feedback trade extension for itch.io. It was probably a dumb idea by me, but would be nice if you could take a look, maybe import one of your projects, an give your opinion.
If that is not your cup of tea: The game I am currently working on is https://crashdumpsoftware.itch.io/epsilon-indi . I had no feedback since the last update ... so feedback would be useful as well.
