ShmupIO

Shmup.io is a vertical shoot-em-up game where you have to dodge enemy and bullets while attempting to do the biggest score possible.

The twist is that you are accompanied by 9 other players!

The game will download other player's data and reproduce their playthrough while you play, their ghosts cannot be damaged but their bullets can still deal damage to enemies!
It will also replicate their time of win or defeat, so their ghosts might leave you all alone to fight...

Your ship can only be damaged if attacked in the cockpit, which is the circular area in the center of your sprite, so don't worry about being hit anywhere else.

Good luck!
