I'm a bit late for donate.. isn't there a way to donate and getting the games now? I didn't know about it and I just saw it. Thanks
Unfortunately no. You missed it by about 10 hours.
HumbleBundle is currently doing a bundle to support this same sort of effort, but at a higher price point and significantly less content. There has been some chatter that itch.io may do a bundle in the future to support LGBT+ charities, but as far as I know, its currently just talk and has no specific dates or certainty.
