This game looks and sounds beautiful - the opening cutscene alone had me awe struck - but I could not handle the controls at all. The castlevania-esque fixed jump arcs, with a mandatory roll afterwards; the half-second stagger whenever you hit a wall; needing to figure out walls and not-walls through trial and error; enemies being able to hit you off during your recovery climbing-back-on-the-train animation; most lateral jumps and drop-downs being completely blind; the incredibly slow climb speed; it's just not fun. I almost got stuck on the first level because the door said (A) but wouldn't open, and I went scouring the level before finding out that I had to kill a certain amount of enemies beforehand.
If I'm missing something here or just need to get good, I'd be glad to give it another go, but as is, I had to call it quits on the second stage because I wasn't having fun.
