I was looking at this a few weeks ago and realised that the way the PDA input worked meant it wouldn't work at most resolutions other than 1080p, and even then it was very bugy.

I've re-done it so it's a normal UI thing (not the mildly insane flat 3D object in the game's 3D world that it was before), so the very few people who come across this game can finally be confused by obscure command line puzzles without annoying UI bugs getting in their way!
