Assuming you don't mind some negative feedback:

  * It took almost 5 minutes to load

  * It gets noticeably slow and the FPS drops to a single digit on 
    the first screen with an Ambush.

  * The openings in the floor are way harder to recognize as such 
    compared to version 1. When I fell through one, I honestly 
    thought it was just a pattern on a floor.

  * The Inventory screen needs to some tweaking. It took me a bit 
    to understand where the Sonic Pulse weapon should go on the 
    left hand side.

Overall, purely from the "user's perspective" it does not look like a super improvement over v1. It is more of an opposite given the lag and the loading times. That's not to say it is not beautifully done, it certainly is.
