TBH, the fun in this game lies in smashing and abusing the Reimus in the stage selector scene, not in banging your head against a wall from the rage of actually trying to play the stages. Granted, I did complete the cave stage and made it to the Moge Flan in the Viet Cong jungle bamboo sticks stage (before getting stuck), but that's when I stopped putting fruitless efforts into these stages out of concerns for the welfare of my keyboard.
