Coming to the software, it is a familiar OxygenOS 11 but with PAC-MAN-inspired content available across the board. There are PAC-MAN inspired themes, wallpapers, icons, animations, and colour tones. To add a bit of fun, OnePlus has hidden some content, such as wallpapers, ringtones, stickers, etc, that can be unlocked by completing in various challenges scattered throughout the retro-themed operating system. There is also a PAC-MAN camera filter named ‘Pacnomaly’, which adds retro effects and moving ghosts over the normal frame. Among the many PAC-MAN-inspired things, I liked the pixelated icons of OnePlus apps. However, I wish the icons were available for system-wide apps for a uniform experience and not just for apps by OnePlus.
