First off, I think it's awesome that you released this demo version. Can't wait to get the full game!
I do agree that the manual needs some work. I listened to the TBRN archives where the first 15 levels were shown, which bTW are pretty interesting. I also played the old beta 4.1 version when it was out. So I know how the game works, but I can see how it could be confusing for new players. What I think the manual needs is some starters for navigation, perhaps examples of how to scan the surroundings to determine a safe path across a hazard or just assess the area. Of course that's up to you, I'm not saying that even a newcomer to audio games must find this easy or anything, but often I see games which draw on each other's mechanics, which is great, but more and more they do so without enough explanation to allow newcomers to understand what's going on. This results in frustration.
I think the shift left and shift right arrows are also a little finnocky, for instance they'll just say a certain number of feet without anything accompanying it. Another small suggestion: hazards should be labeled, for instance, fire pit, acid pit, chasm etc.
One more minor thing, the pitch changes on running footsteps are irritating after a while for me. It really ruins the realism, which is a shame because the other sounds are really good. I'm not sure if I'm in the minority on this or not though lol
That's all I can think of for criticisms. Not trying to be harsh or knock the game, but it still feels like it needs a bit of smoothing out. I will still buy it when it comes out regardless of what happens, because I wanna play the other levels!
Make more of less, that way you won't make less of more!
