I was practicing a speedrun of this game, and on the second level, I went up a staircase, and clipped through the floor. i then proceeded to clip into the staircase and get stuck. Then I clipped through the floor to the start of the level. Am I alone here? This was really funny and I wish I recorded it.

I am new to the speedrunning community with the goal of speedrunning Half-Life 2: Lost Coast without glitches or major skips! Any good recording software that is free anyone can link me please? Thanks!
