Throw Away Games let me know that Robo's World: The Zarnok Fortress will be coming to Steam March 7th. You can check out the trailer below:

Robo's World is a collaboration with Bluish-Green Productions in which you help Robo defeat the Zarnok robots by sabotaging their ship:

Robo’s World: The Zarnok Fortress is an Open World 2D Tactical Action Platformer. Take on the massive, interconnected Zarnok Fortress, and sabotage its crucial systems to halt its advance on your world. Your foe remains ever vigilant, learning from its mistakes and actively repairing sabotaged zones. Play as Robo, who’s about the most nimble machine you’ve ever seen sporting tank treads, and the acting guardian of the planet Saphirium. Master your abilities to take the Fortress offline, dynamically affecting every other zone as you work towards your goal of dealing the finishing blow to cripple the Fortress beyond repair and put an end to the dark reign of the Zarnok.

You can add the game to your Steam wishlist here, and follow both developers on Twitter.
