You may or may not have heard of my game Space wars, but i am running out of ideas for updates. Does anybody have any suggestions?

Not a bad little game you have there. While not a feature so much as a game play improvement, see if you can add more than one projectile on screen at a time. This may be intentional, of course, but I found it a bit annoying to be unable to fire more than once, especially if I missed something. Another suggestion would be the potential addition of boss fights, although that would be likely to require some restructuring of the game to make them occur at certain intervals. Good luck!

Good idea i'll try that by decreasing the clone time.

Hello! I like the game.

Here are a few ideas, you may or may not like them:
–more power-ups
–different enemy-creatures, some that you need to shoot twice, some that fire burning blasts at you
–speed up game time. This is a big one. I got 23100 points (the high score, but it wasn't saved–I'm a New Scratcher) and it was rather dull for most of the time because it was all the same. If, say, the enemies came faster as the game went along, that would make it a little more interesting.
–I like @Moosemeister 's idea of boss fights.

Good luck!
