can we add agent difficulty to single level and full game runs? ive been doing agent and i wanna well put some runs up on the leaderboards but there is no agent difficutly on the boards.

Agent is a slightly different difficulty [to Operative/00 Agent] in the game, which, if added, would just fragment the runner population and stall the optimization of the speedrun. What the Agent difficulty adds to the speedrun is very minimal [compared to what 00 Agent difficulty adds to the Operative run]. Operative is the easiest difficulty of the game with least amount of objectives, while 00 Agent is the hardest, with most amount of objectives. I suggest running either one of those difficulties if you want to compete with players on this leaderboard.
