I've had a lot of fun with a free game jam game on itch.io with an in game timer. I've also seen runs on youtube but no forum or place to talk about strategy and compare times. If you haven't seen the game you can check it out here - https://squidcor.itch.io/anger-foot . My best any% time has been 1:24 but I'm sure it could go lower and there is also a 100% run where you need to kill all goons.
