Oh no, a ton of coding has been done...
SQ1 about 85%, need more sounds, and more looks but can be played all the way through
SQ0 about 75%, can be played all the way through, but a bit buggy in places
SQ2 about 80%, can't be played all the way through, but only missing a few elements that make that possible
TLD 0%, that things just massive and haven't delved into it too far yet
SQ3 about 45%, most rooms are present but overall, very fragmented
