In my quest to get the boss key, I'm stuck at the room with the three geysers and the tektites. I killed the tektites, and I'm now trying to jump over the geysers to the other side of the room. The problem is that I can't jump to the first geyser at all. I just fall against it (see screenshot).
Note: I'm playing on the project 64Project64 emulator version(version 1.6).
