The new build is great! A few little suggestions:
It might be a good idea to allow the player to run as there's quite a bit of backtracking.
The text size is a little small.
Some way of highlighting all interactable objects in a room would be handy.
The melee combat is pretty bad (repetitive and easy). I'd recommend scrapping it and finding some other way to do it. Such as introducing more stealth, adding a gun (that you aim with the mouse) or making the encounters more like Another World (insta-death, puzzle-like encounters where you use the environment to your advantage, etc).
These are just my opinions. Feel free to ignore them! It's a very cool game with a lot of potential. Keep up the great work! :)
