Thanks very much for your kind comments. You've given us plenty of useful feedback, so it's all welcome. :)
You're right to point out that the report is not as polished as the part where you identify the bodies. We struggled a bit to meet the jam deadline, so we couldn't put as much work on it as we would have liked to. Regarding your questions, please find some tips below:
fvzcyl pbyyncfrq -- . Technically, your answer could be good (so we'll need to remove it from the choices), but the answer that probably makes the most sense in the context of the report is raqrq hc genccrq
cerffhevmrq tnf --. The crucial bit here is "entered through". This gap is associated with opening the fire door, in a context in which someone was already trying to open the carpark door (which was partially blocked). So what "entered" did so from the outside. This means it couldn't be cerffhevmrq tnf. The correct answer is pyrna nve. Our reasoning/wording could be clearer, though. Thanks for pointing it out. [Incidentally, we planned to include an additional gameplay layer for fire dynamics that would have made this self explanatory, we just didn't get around to it.]
rkcybfvba --. You can check the PD reference manual for arson to get an additional clue here (it's towards the end, I believe). The correct answer is sveronyy
urael --. I guess urael got killed too, so you're not wrong, but the report mostly refers to cnhy, that was our logic. Still, your point is valid, we need to improve the wording of the last sentence or simply add an option that reads ("them both").
Also, thanks very much for encoding your answer to avoid spoilers in the comments. Really clever!
