I am almost sure the engine used is tyranoscript
Another proof
This was next level scary.
The whole atmosphere was super creepyand every noise made me jump.
The jump scares were perfect but it wasn't just about those cheap thrills.
The game really messed with my head.
I couldn't stop looking behind me, even when I wasn't playing.
It felt like I was actually trapped in the game.
I really love it
The story is also movie script quality level
I don't wanna spoil but that scene in ending D took my surprise.
I did not see it coming.
Overall I really enjoyed this game I can see a lot of hard work has been put in to it
and one of the biggest if not the biggest fan of the Zero Escape series.
I also really appreciate the fact that i can name myself whatever in the game and
that there is no limitations to the name you choose. You can choose to name
yourself the most offensive name ever and the game simply allows it.
Naming yourself a very long name also works and there are no limitations to the
name length
The game mysteries are also very intriguing but probably more enjoyed if you play
the prequel for this game which I found through the link you provided on the game page
One suggestion tho is to consider adding a Linux version for people who dont want to use windows.
Oh and the ending song of the game reminds of a very old but popular song called Down. I don't know if any zoomer even heard of it
