Hold up -- thank you for that bit about the death code. I tried it out in my own copy and couldn't replicate it, but I'll definitely be on the lookout in case it happens again.
Otherwise, thank you so much. A straight-up tutorial isn't on my agenda, but I am probably going to add some stuff which eases players into the game a bit more smoothly. Keep in mind that the demo isn't fully polished, too; the final version's gonna have an intro cutscene.
