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.
