Cyborg Ninja Mayhem is a twin stick shooter made for the "GitHub GameOff" jam.

The jam's theme was throwback.

So you control a super amazing 80's cyborg who throws bouncing shurikens at invading spiders, how long are you able to hold out?

Controls : WASD or Controller Left Thumb Stick to move up, left, down and right respectively.

Arrow Keys or Controller Right  Thumb Stick to shoot in directions.

This is fun!  Web version is not working for me (Ubuntu 17.04,  Chrome 62) - it runs, but the input seems to think I have keys stuck in the "down" position.

The Linux download did work for me, although the ".exe" extension isn't needed and I had to manually make it executable (`chmod +x`).  Very nice feel with the sound effect and screen shake when a bug is hit!

Good to know the linux version is working!


pretty cool! (although the shurikens are a little glitch and if you shoot them when  moving you get bounced a bit)

I especially liked the BG pattern!

Thanks a lot, I hope you had fun playing!
