Hi, I think it would be so much easier for a blind person if when you scan for an item, if you can't find it but the scanner makes a beep sound indicating something is on the right, that your character should be able to face that direction and the panning should indicate that.
At the moment if we hear something on the right then use the right stick to pan to the right and press x/the scan button, the sound is still on the right and not in both headphones, this is honestly very confusing.
Also maybe you could make the thing that grabs multiple items a bit cheeper or easier to get.
Another thing is a learn sounds mode and a tutorial would probably be nice.
I noticed you added a mini tutorial for each upgrade system now which is really nice.
I do really like this game but like others on audiogames.net I do find it confusing from time to time, there's not really a sence of where you're going really, I know it's a masiv infinet world or at least I think it is, but at the moment I feel like I scan, try to turn to face an object that the scanner isn't leading me to but is suggesting is there and then I either walk for so long or keep scanning and don't feel like i'm getting any closer.
Oh one more thing, is there a built in updater, that would honestly be easier than grabbing stuff from ich.io each time, if there isn't, please make one if you can.
