@fastfinge, @blindjay and everyone else dismissing this game,
Sorry to say, but if you ask me with this attitude you're really a disgrace to all blind gamers and you should never advocate for game accessibility. If you want to stick to the audio game developers, be my guest. Just remember that those amazing breakthrough developers charge 4 or 5 times the price of skull girls for games that have draconian and unfair DRM, and very realistic physics that put you in control of a plane that weighs 50 kilos, climbs to 50000 feet in 20 seconds, and decelerates from 1000 km/h to 0 in half a second. Or games that make you drive a car down a railroad, because it's too difficult to make a game with, you know, actual roads. But never mind that man, it's amazing and empowering, and state of the art!
So you don't want to support the developer because of the platform he's using? OK. Just know that Valve only receives about 20-30% of the revenue. I wonder where the rest goes to? Maybe zero labs, the developers of the game, the same people who spent 2 days non-stop to make it accessible for a small fraction of the player base. But no, I can't do that because it's a disgrace to the blind community. Just remember that apparently they don't care.
So let's just blame Mike for making the game accessible, and using a platform which has a very good multiplayer infrastructure that can support the hundreds of thousand players at once. But OK, let's look for alternatives. Games for windows live? Inaccessible, and it's due to shut down desura? Even more inaccessible. Game centre? It's not on Windows. They could just run their own servers, but to have them for every world region, be up 24-7, it would cost a lot of money. And keep in mind this game was crowd funded by gamers who actually wanted to see this finished.
Steam can be used without OCR, it's clear you haven't read the guide. The captchas can also be solved with webvisum, it just takes time. Supporting multiple screen readers? Well, that's what you get for probably using JAWS, which by the way is getting the most important bugs fixed since.. Oh, V8 maybe.
So with that said, have fun playing your audio games. And good luck approaching mainstream developers with this attitude!
