Fans of crazy action might want to have a look at what Teslagrad developer Rain Games have coming next, with a demo of Knuckle Jet out now. It was revealed back in March 2025 and while unfinished, they're ready to see what you think.
In a press email to GamingOnLinux, Rain Games said:
"Coming off Teslagrad 2 and being nominated in 6 categories for Nordic Game, as well as a nomination for the coveted Annie awards, we at Rain wanted to make another physics driven platformer. This time it is a little different though.
Knuckle Jet is faster and smashier, with vibes straight out of a Saturday morning cartoon, and an artstyle that looks like its associated toy series, we promise to deliver something quite unique.
The game is set in the same narrative universe as our Teslagrad games. Though the story stands alone, there are many characters and background threads that existing fans will recognize."

A rogues gallery of despicable villains!
From high-rise clockwork cities to soot black forests, each biome in Motorland is under the grip of the power-hungry industrialist Tychoon and his band of business associates. They've kidnapped an entire orphanage and put the little ragamuffins to work amongst the crushing pistons and spinning cogs of their robotic death machines. It's up to Anastasia to crush this cadre of conniving crooks before facing the ultimate foe.
Drop into battle together with a friend!
It is nice to have friends. It's even better when they can join you in battle! Fight together across the main campaign, or beat the snot out of each other in a friendly game of Knuckleball.
