Jump into the slimiest weapon frenzy platformer game to play and create worlds to share with your friends! Don't just push buttons on the controller, make the jump to Jump Maker! The game is best with 2 players, sitting together with controllers in hand designing levels together in creative mode.
Action, Indie, Early Access · More free games
Design and jump through creative, slime-filled worlds with a friend using controllers in Jump Maker. This indie platformer pushes beyond simple gameplay to encourage collaborative level creation.
About this game
You are a slime, the weakest of the monsters, living in Gloopia. Squishing, slicing, and shooting his way to the top. You wield weapons, collects keys to unlock chests and power cells to power portals.
Throughout Gloopia, you will read signs hinting at who is pulling all the strings. Fight orange wormies, skeletons, turtles and more in the Jumpit to Thumpet world.
Use Creative Mode to make fun challenges for your friends. Play around with the different platform types, resize them, and add collectibles. Make puzzle levels, speed running levels, fighting levels, etc.
All players are able to design their own levels to add to the game. (I have the discretion to disallow any level that includes vulgarity)
The settings room has interactive toggle switches and a cheat room that has a secret entrance; players can adjust their nickname in this room. In addition, there's a fun and unique paint booth to change the slime's color.
