I've really enjoyed a bunch of games in this bundle, but I'm also aware that a lot of the people who donated their games aren't necessarily doing super well themselves, especially in the pandemic. I've seen forum posts about how people who liked a game can always go and rate/comment/purchase it directly, but I think also it would be really amazing if itch.io could help prompt some financial support for creators. I don't think it has to be anything beyond a one-time email a few weeks out to all bundle purchasers saying in effect "if you liked the games in this bundle, consider tipping the creators" and some links with easy ways to do that.
I don't know if this would mean linking games that have actual downloads attached to the donator's email, or if it could be constructed as a general fund that all tips go into and creators in need could access, or something else. I'd be happy to help (for free, of course) build a process if there's a need for some extra hands with business analyst experience. I just feel like there are going to be other bundle purchasers who wouldn't mind showing some extra support for creators if it is made easy for them to do so.
EDIT: come to think of it, creators themselves are probably the people whose opinion about tips is most important. I imagine if given the choice to be included in something like this, some would want to be and others would probably prefer not to be. That should probably be a consideration.
