Tonight, Thunderful hosted a livestream of announcements, including a new SteamWorld game and a release date for The Gunk from SteamWorld's creators. They've also put a bunch of their games on sale, including giving classic platformer SteamWorld Dig 2 away for free for the next 24 hours.
"The platforming controls are welcoming and smooth (you can climb any flat wall just by repeatedly jumping up it) and levelling up is a steady, mellow slope, rather than an awful grind," wrote Brendy upon its release. "Much of that is simply the game being kid-friendly, but it’s also 'fed-up-adult-friendly'. There’s something soothing about devoting twenty minutes of your evening to digging for your next robo-power, or the next milestone in this light-hearted story of greedy robots and idiot, mutant humans."
Thunderful also have a full publisher sale on Steam and on GOG. That includes 80% off SteamWorld Heist and SteamWorld Dig 1, and 65% off SteamWorld Quest, all of which are similarly wonderful. (They also make some non-SteamWorld games, too, but have a look.)
As mentioned above, Thunderful also announced the next SteamWorld game at the show, and it's another new genre: a co-op, third-person action-adventure. There were a bunch of other announcements during the full Thunderful World livestream, presented by Mark Hamill, which you can watch over here.
