Nice game, the multi-player setting is really funny. 

Would you also check my game

Can't say much about how fun the game is since I had to play solo, but the controls work smoothly. It's a well-made game!

Most of the visuals work, particularly the shots, but the ships are really tiny and unnoticeable. They should be the most distinct objects on the screen. Maybe make their colors stronger to contrast the gray asteroids.

Some different death effects would improve the game - the most glaring one is the black hole which seems more like a solid object when you crash into it.

great work !! nice game well done dude !! i liked the game design and the graphics ^^ 

btw i rated ur game can u do the same pls ?? and thx !!

Nice Multiplayer setting. I really like the concept and the idea of the Theme.

Great work :)

At the start the spaceships where a bit too small, I did not see them at the beginning, but then I had quite fun with the mechanics. Reminded me of Asteroids a bit. I liked it, perhaps consider bigger sprites for the spaceships, I think the space is here for them. :-) 

The gravity mechanic is super cool. I think there definitely needs to be some sound or other feedback when you get hit by an asteroid, but otherwise nice game!

The way the gravity affects the bullets makes it an interesting game! AMazing!

Really cool game, a bit short and simple but you reproduce the Asteroids gameplay very well and the black hole / portal addition is a lot of fun, especially because the bullets travel it and the gravity attraction ! 

It would have be cool to have a scoring system with an instant respawn instead of a replay button freezing the game to pace it better and track the scores, and if the asteroids splits themselves into pieces like in the original ! 

The controls were a bit too forced. But the graphics were cool.

Looks cool, but I haven't got anyone to play with. I'll still make some observations tho, first up is that the resolution doesn't seem to be correct, and I can't see the edges of the screen, and the players are not visible from the start. It is also hard to tell which way you're facing, as the front of the ship looks very similar to the back of the ship. I'm also not sure why you'd use the teleporters, they're often close together and seem a bit unnecessary to use. Perhaps there could be some interesting mechanics arising from this, like perhaps you get a speed boost by going into the portal, or  maybe there could be a lot more portals and portals are almost a hazard?

I can't say that I actually played, so no comment on that, but hopefully these little nitpicks can help with polish =)
I also need to mention how nice the spacey graphics are, and the neat ambient music, nice mood!

Fun game to play! The gravity of black holes affecting bullet paths is awesome! Single player mode would be nice though, score by shooting asteroids or something like that.
