@ -473,3 +475,4 @@ Breakout 71 can be installed and work offline in many ways:
The game should perform well even on low-end devices. It's very lean and does not take much storage space (Roughly 0.1MB). The web version is supposed to work on iOS safari, Firefox ESR and chrome, on desktop and mobile.
