I believe they accept Paypal, but not crypto sadly.
We're still checking over some issues we're running into with the next update, but I'd say roughly to give some wiggle room for error. It could be possible for a new release on May 31st, but we'll know for sure during the weekend. Otherwise the safe bet where it'd be released regardless, would be around June 4-5th.
The flip side is that we're already getting ahead of ourselves by getting some of us to work ahead on episode 5 (as we're getting ep 4 ready for release). We're expecting easily a late June release for episode 5 and from there about every 30-35 days tops for new releases.
