After finishing first level (it takes 31 waves) it crashes with: thread 'main' panicked at src/dyld.rs:604:9: Call to unimplemented function _CFURLCreateStringByAddingPercentEscapes
Briefly fades into intro screen before crashing on "Object 0x375fa270 (class "NSUserDefaults", 0x374f7910) does not respond to selector "dataForKey:"!"
