Version history

1.0.3
What's New: - General improvements and fixes for things that were working suspiciously well - Fewer bugs. They didn't disappear — they just moved to a different carrier - Slightly faster now. Roughly one signal bar's worth Thanks for sticking around. Your 2004 phone would be proud.

This update is all about comfort and clean sound. Portrait mode — flip your phone upright and play one-handed. AMR audio support — every beep, blast and melody now plays just right. Slimmer CPU usage — smoother gameplay and a happier battery. Same retro games, now even better.
