What are all the different easter eggs you can find? The rules say there are many throughout the game but I've only found the one in the first room. Interested in this because I'm looking into optimizations for easter eggs runs, with what I've found so far it looks like it could potentially be faster than non easter egg runs and I'd like to know if there's any timesave I'm missing out on

yeah the easiest one is in the first room but ive accidentally triggered another one in a separate room and never got it to come back. there are more out there but it requires looking into the code to figure out and i havent done that
