Ehhh, I think criticizing a game engine for having a lack of accessibility is fair; yeah, maybe it's just a case of 'time to get a new keyboard lol' or it may be something more serious, like someone who's physically impaired. My hearing's impaired, and there have been time in multiplayer games where it's prevented me from hearing teammates or missing audio cues, to everyone's lack of enjoyment.
That said, to rake Sierra over the coals for not including those features
is a little unfair- as far as we know, she's the only one doing the programming for a game that (so far) is 50-60 hours long, with other staff only doing art. True, I don't know much about programming part from 'press button, receive fun', but there's so much work done in TLS and its engine I'm not sure how easily it'd be to port everything over into a new, more user-friendly version. From what I've managed to research (aka 30 seconds in Google),
You must be registered to see the links
to transfer VX Ace assets to MV or MZ, so maybe Sierra might not see the worth in porting over her already-completed work to newer engines.
As things stand, the best I can suggest for anyone who has accessibility problems is to play with the numpad, since all the keys you really need are right there. I'm not sure what other physical problems would prevent someone from playing TLS, but if anyone is interested, and is willing to ask questions in good faith, I'm sure that the people here can help out.
