No problem! It's really nice to see a comment on this every once in a while.
I'm currently pretty busy with school work and other stuff which is why the game hasn't really got a lot of updates. I would love to update it some day, maybe next years Dream Diary Jam? (hopefully I won't be as busy)
as for the snake girl, she can be found in the game currently. She's in the one world that's a bunch of the same room repeating with slight differences, it's kinda like the backrooms if you know what that is. The world isn't as big as it looks so finding her isn't too hard. You don't get anything for seeing her though she's just kinda there.
Thanks again for playing!
