Humble Humongous Back to School Bundle (end date: 2021-09-17 18:00:00 UTC)

The first three bundles last decade were followed by a sale last year and a fourth bundle now: pay-what-you-want ("Adjust Donation" to see the Tommo/charity-of-your-choice/Humble split and customize it, though the slider for Humble doesn't go below 15%) $1+, $[more-than-the-average]+, or $14+ respectively for 11, 20, or 37 items (games and bonuses, though I don't know how the Five-Track Original Soundtrack Sampler compares to the Bandcamp versions of those five tracks).

Both the soundtrack sampler and the digital art book were already available in a much more expensive, but permanently available bundle that was discussed here.

Unless you're missing some of the games, this really isn't worth picking up. The soundtrack sampler is just an artifact of the time when Tim unsuccessfully tried to work with Tommo/Billionsoft. Now that the full soundtrack is available, there's really no point in getting this tiny portion of it. And the art book is just a few pages of low-res development and promotional artwork. There's really not much to it, and you can find some of it for free online.
