The new Powerslave is pretty dope, but i want to mention some issues:
the length: i completed it in 4 hours. Didn't hear anything about this rerelease before, so when I saw it in my brothers Steamlibrary, I had no prior knowledge about the complete package. The original releases were fairly different, so I honestly expected to merge them somehow - especially because there are no secrets to discover (other than building the transmitter). That leads to the game being incredibly short. As I said, I needed 4 hours to fully complete it and I certainly didn't rush through it - played on the 2nd highest difficulty. When compared to Blood, it just feels like a first episode.
the hitboxes: yeah, I just couldnt really get used to my own hitbox. It is just a very weird one! The x-axis is (or at least feels) much wider than the y-axis is tall - so you are essentially a floating cupboard.
Other than that it is a very fun albeit short experience.
