There’s a steam workshop mod which puts a checkpoint in all the temples, this let me beat it, the base game only that is, no challenge runs or secret bullshit, haven’t even attempted that.
I do enjoy setting everything on fire and exploding myself though. I played a fair few hours on and off.
That’s true, fairly easily avoided by holding the up or down trigger until you’ve got a clear line of sight to your target before engaging autopilot.
