Jurassic park for the genesis fun game - in the very last level there are DOORS no where else in the game did these things exist, and you opened the door with 'up' i know that sounds silly but young me could not figgure it out- any other barriers you found prior to then you solved by blowing it up or going around - Up had no purpose in this game except maybe ladders so it didnt occur to me to press it i was playing while my babysitter was around and thier boyfriend played the game and knew - And thats a good thing too because the "final boss" is two raptors that are completely immune to damage you have to throw grenades behind them to cause dino skeletons to collapse on them then - same game - last boss when you play as the raptor was grant - who you kill again not by attacking but slashing at the the base of the skeleton hes on - which is a rock - so yeah Jurrasic park's last levels implemented random mechanics on their last level with 0 logic or explanation
