itch.io

Just played through the demo and I really liked the concept, the atmosphere and the sound bits. 
HOWEVER, as a sound designer I have small fix to suggest. When you open your laptop there's this humming soundscape which starts playing and then stops when you close it. I'm going to assume you're not using any fades for that loop when you do so; the result is that it's quite easy to produce audio artifacts because of its sudden interruption. Try to put a 0.5 sec fade in and out times for that and also potentially to any sound which is prone to cause this. Easy fix! ;D

Hope this helps! Just wishlisted on Steam as well!

This project is developed in UE4 and has nothing to do with legit PS1 games. It's never going to run on real hardware.

Concerning the music, you're overthinking it. It fits the game and that's what matters. ;D
Amazing work!!!!!!!!

I got this in THE bundle but it is so relaxing, simple yet brilliant and enthralling, that I purchased it again!
As a small suggestion I support what was already mentioned in the previous comments: more in-depth graphical settings.
I also have something else but might be not-doable/sci-fi: would it be possible to have the shapes interact physically with each other only when the user interacts with them first? It could prevent the stuttering for big towers even when the building is freshly built (and perhaps "premature collapsing" also). 
Thanks :)
