Much faster startup — opens almost instantly instead of a ~2 s black screen. Fixed a black/blank screen while a level was loading. Fixed daily reminder notifications not being delivered. Smoother gameplay: removed stutter when nuts land and when finishing a level. Clearer nut colors — no level pairs two shades that are hard to tell apart (incl. blue/cyan). Star ratings and the boss move limit are slightly more forgiving.
