I'm super impressed with the first hour. Feels like the first time I played Gravity Bone or Thirty Flights of Loving again.
The only things I've brushed up against are performance hitches, no mouse sensitivity control, and the early advice about taking notes and using multi-jump should perhaps also mention "save manually!" (I did not know you can save whenever so I died twice and had the game crash once, so each time I had to restart from the beginning before I realized saves are manual.)
Otherwise, man I am digging this game.
