I played mostly for the nostalgia value from back when the original game was on flash.
Biggest thing for me is, the controls are not great. It's not very responsive, death animations are slow, landing surfaces are very small and unforgiving at times, and the leap... I wish there was an easy way to tell how much I'm going to be dashing, because it's an important mechanic. It helps you move faster horizontally, but doesn't tell you where you'll land, which is frustrating.
It teaches you to think and solve puzzles, then it makes you do precision platforming, then suddenly there's a boss fight, then there's stealth section with unclear lines of sight... it's kind of all over the place and there are certainly good stuff in there, but hard to say that the overall experience is enjoyable.
Aesthetics are pretty neat, with the blood falling off through the floors, that I must admit. It's a bit goofy when there's blood dripping from the ceilings and the enemies are completely oblivious though.

I didn't know it was going to be so difficult having played the original flash game and seeing it wasn't THAT bad. And yet, the game not only demands precision platforming, but also has the nerve to make you build and lose velocity where your character doesn't stop or start moving immediately, causing you to conveniently slide into the many obstacles it will throw your way, as if dying upon being hit wasn't punishing enough. The last straw was this room full of lasers and an acid pool with narrow platforms to jump on, which gives you the smallest margin for error. It is very frustrating. If I had known Vox Populi Vox Dei 2 was going to be some B.S. like "I Wanna Be The Guy", I would have never bought it in the first place.

Play this game if you like B.S. difficulty platform games.
