I absolutely love this game so far. You've done an outstanding job replicating the feel of Bloodborne on the PSX. I do have a few questions/QoL things I wish you could add (if you see this post).

Would it be possible to add analog support? (This isn't entirely out of the realm of possibility, OG PSX controllers didn't have analog sticks, but later versions did)
Also, maybe a bug, but I noticed numerous times that my AUDIO settings were not being saved between "Loading" zones. They would appear to be set correctly in the menu, but they reset back to 200, then you have to fiddle with the slider again to get it to recognize it's much lower than that.

The control scheme is not at all likely to be changed, and options for it are very unlikely to be added.

A way around this is to add the game to Steam, open Controller Configuration, change your left joystick input type to Directional Pad, assign the 4 d-pad buttons to the 4 directions, change your right joystick input type to Directional Pad, and assign Left Trigger to left and Right Trigger to right, leaving up and down blank.
