Wow, I didn't expect the first few levels to be that hard I'll edit all the levels today.
Anyways, deadeye I use the platform behavior and time delta for the moving spikes. I haven't tested it on any other computer, but I had a feeling the platform behavior would screw up. I can if need be make a custom movement behavior, but it would probably change the whole game because I need suspended jump.
EDIT: BTW, the music changes every 5 stages.
