I rarely "rage" at a game, but that boss was straight bullshit.
Lol takes me back to 8bit and 16bit era's. Platform games.. OMG I still don't like platformers for that reason. One missed step due some dodgy physics, collision detection or camera angles and it was back to the beginning!
I've literally thrown disks of bedroom wall in rage. Hudson Hawk was my worst 'nerd rage' experience - stamped that bastard disk into oblivion.
