First time I played this game a while ago I was unable to finish the second level because I got lost. Tried to replay the demo today and I see some added roadsigning and the ladder in the first level was also adjusted but I'm stuck just the same going back and forth. after I got to the gate in prison that require the yellow key I wasn't even able to find my way back and I was running in circles for half an hour before I found a way to the start of the level. I rarely have this much problem finding my way in similar games. It doesn't help that elevators and seem to be designed to work only one way - especially the long one - when you're up and want to get down you will fall down the shaft and then it will lift you back up before you;re able to walk out... this needs to get fixed because it signals that going back is the wrong way to go.
I found bunch of new secrets but I was not able to find a way to progress - means that's something is wrong. replayed for the third time just to be sure. I scavenged every inch of the level and the underwater sections and when I get to the yellow gate I'm stuck with no way to go.
I watched a playthrough and it looks like there's a door that looks like a regular metal wall with no indicator that it can be simply opened and it doesn't look like any other interactive object in the game. I think that's the culprit. also I saw a gate that can be opened only from one side - again no visual indicator that it's the case. You should make all interactive doors be visually obvious - unless it's a secret. Also there are certain levers in the level that when I flip them I have no idea what they did - this also should be addressed.
In other news - katana primary attack works much better now
also - rebinding keys has no effect
