I made a multiplayer web browser game

The demo is empty. It needs some motivation to keep people there. For example other games have coins that you can collect (moving coins? gold meteorites?), or even a few npc like an ufo would add some objective while waiting other players.

what can I do with the oney? Can I buy amomo or health? How?

It's very difficult to navigate spaceships. I made a somewhat similar game with only one star a long time ago so I remember some tricks fot I had to play a few miutes before my fingers got rememebered the tricks. I'm not sure if it's a good idea, but it would be nice to show the currrent trajectory and the trajectory if I continue to press the forward button as dotted lines.
