need some ideas for my game

Hi !
Now have added a scrolling map into my game. Have you some interesting and easy ideas to add ?
Thanks

i've enemies :-)
i've tiles, canon, rotating ball with chain, some bricks, doors...

Vortex which drags you towards it.
Parallel dimension where controls are reversed.

I think what you should be asking is what are you trying to do with your game? Is it a strategic shootemup? a frantic shootemup? Is it a game with limited resources or one where you just need to destroy everything on screen? When you've established this, then you can begin to detail a list of enemies/game systems etc that will support this high level vision. Do this, and you'll get a more focused game, that will be a much stronger experience for the player and therefore a better game...

just a classic shootemup ; you just need to destroy everything on screen !

You know what I always liked - I think its an idea already out there (the guy who did Lumines, his next game uses this) but a self destruct option which the player can use in a situation in which they know they are going to die - the player can detonate his ship and cause it to explod, but its blast radius is quite large, so it takes out enemies within a close vicinity. Makes for very interesting gameplay!

Nice idea. There are others screenshoots it you want, see my sig.

I might code like a fairy but I can design like a demon ;-)
