I've played enough of these to not expect an error free playthrough, but this is the buggiest mess I've ever attempted to play. Walking through or up walls, some doors allow you into another room, some doors hide your character, while others let you walk up the wall, and interactions that appear to be quest related, but allow no interaction (looking at you woman who lost her keys down the sewer grate.) Lastly there is no clear order to events, how to trigger them, or where to go next. The spelling errors and poor English are the least of my concerns here. Good luck to the dev to figure out how to fix this. Right now it is unplayable.
