Fatal error sounds bad. Is there anything else written in the error message? And what System / Operating System are you trying to run the game on?
A quick online search only gave me very old results (ca. 2017) about fatal error in connection with "D3D device being lost" on Unreal Engine games, which seemed to be the result of old, or broken graphics drivers, or old graphics cards being used. In rare cases it could also have been caused by more modern and overclocked graphics cards.
If it happens because of older hardware, then I'm afraid there is not much that can be done about it.
I love this game, it's feels really nice to play this formula in a familiar place like Peach's castle. This idea has a lot of potential and it would be really nice to see this done with other areas like the basement and courses and even other classic games. There is just one major problem I have with the game, and it's that anomalies can appear right in front of you. This makes anomalies that could otherwise be subtle and fun to find way too obvious, which is a shame and definitely something to reconsider for any updates or future instalments. I'd suggest a script that checks the camera the player is looking at and delays anomalies appearing there until they switch to a different one. Once again, really good game, it's fun and the anomalies are well-made. I hope you keep making games, of any kind obviously!
Hey that game looks great! There's a french streamer that played your game during a twitch stream and he loved it as well! You can check the youtube video of that stream to see it, he even got a message for you at the end! (Timecode: 29:35 (his english sucks but it's understandable))
I hope this game will get more updates, it have great potential :)
Happy Halloween! Came back because I had to share that the Halloween Video I made is up! I'm sure you've seen a dozen people play your game already, so I'll just say that my actual review section starts at exactly 39:18 if that's all you wanna check out!
All in all, this really was my 2025 Game of the Year, and I hope the review reflects that!
Oh wow, thanks for the positivity! Really made my day! It is really fun to watch people play the game and miss some of the anomalies while I'm shouting at the screen. I often hope for RNG to trigger some of the crazier anomalies, like the big toad on camera. There's another fun one in the Bowser Corridor that I really like that did not happen in your playthrough.
But I'm happy to see you had fun! And Happy Halloween!
I'll be totally real, I STILL have the game installed, and have played it a few more times off camera! I think that's why I've been so in-thought about what other cameras and anomalies could be added potentially in the far future!
I'll still be playing it when I have a free moment, and I hope I can find all the other anomalies!
Sorry, just had another really good question aside from looking for the soundtrack! This game was super good, do you ever plan on adding more to the game? Potentially Cameras for the Basement Hallways and the Hazy Maze Room? I would LOVE that as a harder difficulty option! Sorry if two comments was a bit much!
I thought about adding either more levels from Mario 64, or even other N64 games, but currently I don't find the time to add more. Adding difficulty to these scenes is a challenge since N64 games generally have fairly simple or empty levels, so it is often quite easy to notice when something changed. But I think it's okay to have an easier Observation Duty game compared to the usually very cluttered ones.
Will be recording this for Halloween on my YT tomorrow but I wanted to ask, what's the background music? It's very good, can I find the track anywhere to listen to outside of the game?
I will, thank you! And the Music for the background is very nicely made! I think it would make a really cool individual track to post somewhere if you ever felt like it! Super spooky and ambient! Just a lil' food for thought!
how are you supposed to report a missing boo? One in the courtyard disappeared but no matter where I clicked, I couldn’t report it. What am I supposed to do?
I already played this game 2 months ago and I liked it. As an observation duty player, it’s not that hard to spot anomalies. By the way, Vinesauce just played your game.
It was quite challenging to find things to change in these simple, mostly empty N64 rooms that wouldn't all be obvious at first glance. But I figured it was okay for it to be a bit easier than the usual cluttered Observation Duty games.
The funny thing is that I got the Vinesauce video on my YouTube homepage recommendations. I was quite surprised to see that, and I'm happy that the game has been noticed.
Really enjoyed this, especially how it feels like a much faster paced Observation Duty. Had a liiiittle trouble finding the exact spot to report the missing ghost.
I see, sorry, this was my mistake. I thought I could save a few mb filesize by not packaging in the extra prerequisites installer, assuming most people would already have those files insalled on their systems from playing other Unreal Engine games. I have added them in the packaged zip file. Unreal Engine automatically bundled the installer in the folder: ObservationDuty64\Engine\Extras\Redist\en-us\vc_redist.x64.exe
In case the launcher does not automatically run this.

my OS is a windows 11, and nothing else is written in the error message
Dang, that's not a lot to work with.
I'll have to be honest, I have no idea what it could be then.

Glad to hear he likes the game.
I hear a lot of people asking for more, so I will really have to think about it.
Loved this!
I got frustrated with this game. What am I missing? The things it's telling me, at the end, that I missed, didn't even happen?

What on earth is "The Spook Is Over"? Every time I finish a game that anomaly is the only one I missed and have no idea what it is
One of the Boos in the Castle Courtyard has disappeared.

The background music was just for this game, I never uploaded it anywhere else. Have fun for your halloween video recording!
I will, thank you! And the Music for the background is very nicely made! I think it would make a really cool individual track to post somewhere if you ever felt like it! Super spooky and ambient! Just a lil' food for thought!
how are you supposed to report a missing boo? One in the courtyard disappeared but no matter where I clicked, I couldn’t report it. What am I supposed to do?
You should be able to click in the general empty area where the boo was floating around
Good concept but the game brightness is way too dark and you cant see stuff like 'Tree Falling!' Please add a brightness option for us!

I see and that’s good for you as well that your game has been noticed.
Hi Paulor94, do you have a discord?
yes I have. You can find the link to it on my YouTube channel
it's too dark
Really enjoyed this, especially how it feels like a much faster paced Observation Duty. Had a liiiittle trouble finding the exact spot to report the missing ghost.
You should totally cover more 64 titles heehee
The game application won't open.
Hi, did you unpack the .zip file? Or do you get any error message that could help finding out what the issue might be?
Sorry for the late reply.
Here's the error message.
I see, sorry, this was my mistake.
I thought I could save a few mb filesize by not packaging in the extra prerequisites installer, assuming most people would already have those files insalled on their systems from playing other Unreal Engine games.

Thank you very much for your message!
