RAGEN is a 2D shooter game multiplayer set in space, only for android and web, you can play with
friends, anywhere, without registration.
"At any place, at any time, a quick click will get you in a fun game, with friends or with random people all over the world. With a simplistic and yet satisfying gameplay, this game is there to fill in the blanks in your everyday life, to keep you entertained in quick, fun matches. No time restrictions."
But... This game is only a big fail.
I started Ragen in 2019, and I try to get financing by Kickstarter, but Kickstarter campaign failed. I don't know if I will continue it.
You can try the last version:
Developed with Unity, C# and photon for multiplayer.
