No. I could tell the dive button was supposed to be there (and forgot I had to click it instead of pressing space, I'll correct my post so as not to confuse people). Sometimes, the first time I clicked it, there was a line of white text below it -- it might have been a filepath as opposed to an error. I tried to recreate it, but had no problems this time. It was a few days ago I played the game. Did you upload a bugfix in the past few days? Maybe its already fixed.

Was this it?
I didn't implement any built-in error messages, so if this isn't it, it's probably from itch.io or Godot (the game engine). I didn't update the game (I don't think I'm allowed to while voting is taking place), but if this is the message, I can re-theme/remove it to reduce confusion after the voting period.

I believe it was something like that. I think this jam does allow fixing of significant bugs, which is why I had considered the possibility of an update being why I was no longer seeing it because it could have gotten fixed along with something else.
