Secret Rings was pretty good, and I even got a PB. Black Knight was alright, and I finally got the final boss quick kill in a run PogChamp

Secret Rings IGT: 2:06:13 Black Knight IGT: 38:04 = 2:44:17

Edit: Added the total IGT of both games. Might I suggest adding that as a rule for this category? FYI, you need to watch the true end credits of both games to see the final times.
