That was interesting! I played the original Catto Boi series back in the day, and I'm finally getting around to the remake. I like the toned-down atmosphere so far; there's a bit more subtlety and grace to the horror. The 3D models are really cool, and the original soundtrack is a great addition!
Overall, great work! Can't wait to see where this goes.
P.S. The link on the "install instructions" on the download page leads to a dead Mega link, rather than to the Catto Boi Save Utility.
