No problem, I love giving feedback!
I think I was expecting the momentum to go in the direction the amulet was thrown. So if I built up speed falling and threw the amulet sideways, I could launch myself sideways, if that makes sense. I just didn't feel like I could anticipate how the teleport would interact in a way that was consistent enough for me to make use of it intelligently. I'm still not entirely clear on how it currently works, which makes it really difficult to engage with - especially when it comes to solving puzzles using that mechanic.
Hopefully that helps!
I apologize for not having clear mechanics on the medallion, I don't want the player to feel lost when using it. I think your idea for how the medallion should work is interesting and something I should definitely look into. I think it would make the mechanic easier to understand and lead to some interesting puzzles. I can't overstate how helpful your feed back has been!
