Bullet hell (Touhou) fangame

Neat.  I'm also doing a Shmup, though wanna do my own twist on things.  I'm in the process of trying to figure out a good way to get enemies to get loaded in from a file properly.  I'd like to know how you got the blue glowing effects on things.  The whole graphic side of this concerns me.

It's just a sprite with BlendMode.Add

I have a performance problem. Spawning 64-128 bullets at the same time gives a big slowdown that lasts about 0.4 seconds; however after that everything is back at 60 FPS. How do I prevent this? I already "recycle" bullets (I don't create new bullets).

Have you tried spawning, say 30 bullets a frame for 4 frames? To the player that is pretty much instantaneous.

Without seeing your code or anything, my guess is you either have a very poor performing object pool, or that you are very expensive bullet object creation (or insertion). Both acquiring a bullet object from the pool, and inserting it into the list of bullets (or however you track your bullets) should be very cheap and O(1) operations.

If it's happening on the first spawn it sounds like you are creating many images instead of just using sprite copies.

And using Sprite in your bullet class is bad for memory too
