Oh my god I have had it with this game. I had had enough time away from the game after previously losing 5 hours of progress so I picked it up again. I had gotten back to about the place I had left off, which was after completing the Forlorn Ruins. I was exploring some other areas for power-ups before I took on the 3rd section of the game. I went into a cavern where you had to butt slam a pole to block a horizontal laser. On the last slam, the game dropped me below the platform into the area with the laser and blocked by the pole I just slammed down. I was now stuck. I had no other choice than to quit and resume, hoping it picked up my last valid save spot. Instead it put me back at the start of the Forlorn Ruins, about 1.25 hours playtime lost. I guess that's better than 5, but really!
The sad thing is that I really like the game and I want to finish it. But this is just too much.
