I dont know why but I added some lines to my script and suddenly my game became really slow.
Blend:
Cross Heir.blend (152 KB)
Runs at 60 fps on mine, although you forgot to pack the textures.
I made a few changes to your script though. It now follows the cursor in real time. Cool idea btw.

what did you change? I didn’t see any difference. Although it did run faster for some reason. I think it might be because im running it off of a memory stick right now. I will try it off my hard drive.
I meant logic bricks. I turned on true lvl trig on the Always sensor, so it will update, and I turned on tap on the click sensor, so you can add more than one each click.
Do you think I could use part of this for my game?
Oh yea sure. I just made it for fun. Go ahead. Would you like me to send you the packed version?? It looks way better.
Unfortunately, that wasn’t packed 
But no problemo, I only needed the code.
haha… Really? I thought I packed it…I think im going crazy…Oh well. xD
Have you checked your video card? I once had the same problem that my computer lagged very much when i added textures. I don’t know why but blender textures take soo much from your video card while with all other games my computer worked perfect.
I am new to the BGE, but something that “got me” recently was that I had the display debug option enabled. That is great for debugging, but it really takes a hit on the frame rate, especially when you have several properties set for debug.
You can use a program like FRAPS to show the FPS on top of any 3D application. That doesn’t affect the framerate at all. The demo version will only let you record for a limited time, but it’ll let you see the FPS as much as you’d like.
