Hi, I'm starting to run the game and I found you can do a checkpoint abuse at the end of chapter 2. I wondered if it was known, and if it really saves time. It lead directly after the big door with 5 waves of enemies in chapter 3

The other day, I tried to beat ME using only the jump button for fun. I appear you can really beat the game using it exept for some obligatory slide and openning doors or Cel's fight. I think I'm gonna try to beat the game using the less other buttons possible. I don't know if other people already tried it but it's pretty fun to find some routes to avoid crouching and quick turns.
