Cosmos Arena is a local multiplayer action platformer for 1 to 4 players (best played with friends!). The game takes place on a distant alien planet. Play as intergalactic park rangers on a mission to protect the planet and the aliens from a Robot Invasion! 

Available for free for a limited time!

The web build may have trouble with different kinds of controllers. If you encounter controller issues, here are some keyboard controls you can use (these are our internal hotkeys for development, the game is intended for use with controllers):

A -> (A) (for character select and confirm/continue)

Space -> Jump/Boost

Arrow Keys -> Movement

Left Shift -> Shoot (no aim on keyboard)

J -> Skip to next level

This game is in active development! If you don't like playing games with bugs, please wait for our full release in 2019  :)

Your contribution is greatly appreciated and will help fund the rest of our development. We also welcome your feedback. 

Thanks for playing!

Growing ammo is a neat mechanic. I enjoyed reading about your development process in the dev log!
