Brilliant graphics and lighting/shading. Great art design and colour palette. The audio was highly impressive, but really needed subtitles. The writing and voice acting were amazing. Nice level layout too. Excellent creepy atmosphere.
Collisions all work. I found no bugs. Being able to run would've been nice. Clearly showing what is interactive made the game far less tedious. I'm not a fan of having to mouse over every single object to find what you can actually click on.
Is there no way to break the loop? Does the game repeat endlessly?
My take is that this is limbo. The voice maybe that of someone the player character harmed.
