first: the only thing to complain about in this gym is the dark maze, it takes nothing but luck and an immense amount of time to complete unless you bring a torch and keep placing it to gain a little bit of light for not even a second.
second: the lava ladders course is clearly meant to slow you down and hurt you, you have to jump to reach the ladder on the other side while trying to avoid the lava (i though you couldn't have death causing courses in gym?), the water from when you fall pushes you to the opposite direction so you lose hunger at an even faster rate. also, why have so many layers of lava ladders, if you can prove to do it once you don't have to do it 5 times again.
i not trying to sound like a whiner or anything but this gym is made to keep challengers out imo.
