why does my game run so slow in browser?

[NKO]

When I'm in mmf2 and I test it from there I get a solid 45-50 FPS but whenever I export it to .swf it always runs horribly getting about 20 FPS and tons of game breaking glitches. the .swf's only 2.4MB and the frame has about 80 objects. what could be making it run so slow?

Do you have fast loops? They are really slow in Flash.

No, I have a lot of groups though and alterable values do change around a lot.

Do you have a lot of background objects (like a mosaic)?

I used fast loops in a swf game i done.

1 fast loop for each enemy.

1 fast loop for each enemy position and then a seperate one for the player. (mini map).

mmf file mfa (4,066kb)
swf file 1,753 kb)
but i only have three frames.

This is my first ever flash game you need to sign up to view it.

Needs a lot of work but not a bad first try.
