When a new level pops in, you now get a moment to see it before anything can touch you. The farewell words between worlds finish their say before the next world arrives, every world plays all six of its levels, and powerups shaken loose by a shockwave can always be picked up.

Your hall of fame now keeps three lists: your own best runs, the friends who play Plobb, and everyone in the world. Each player appears with their picture beside their name, so you can see at a glance where you stand.

Challenge your friends! Straight from Game Center you can now dare a friend to beat your high score, your fastest full run, or your best time on any of the six worlds. When they tap Play, Plobb starts a fresh round for them and the winner is decided all by itself (on the latest system software). We also made extra sure your scores and trophies always arrive safely, even with spotty internet.

The menu buttons come alive: they squash like jelly under your finger and burst into little stars when you tap them. A new home-screen widget shows your best score in Plobb's own lettering, and who you still have to beat. The arena now has a left and a right: pops, shots and bounces sound from where they happen. Wonderful with headphones. On iPad, a trackpad or mouse now steers Plobb just like on the Mac: glide the pointer and he follows, click and he shoots. A keyboard works too: arrows or WASD steer, Space shoots - and the menu buttons grow as the pointer passes over them.

The six Castle of Nightmares achievements and seven fastest-finisher leaderboards now appear in Game Center (2.2 brought the code; this update switches them on). Everything you already earned on 2.2 was kept safely on your device and shows up by itself.

Menu and pause buttons now feel like native iOS buttons: they dim when touched, act when the finger lifts, and sliding off cancels. Six Game Center achievements chart the climb through the Castle of Nightmares, from escaping the dungeon to the finale for defeating Motts of Psodor. Seven new leaderboards list the fastest finishers: one per world and one for the whole game, timed to the hundredth of a second (the clock stops while paused). Fixed: a weapon grabbed during the berserk transformation now keeps its full time and starts working the moment berserk ends.

New thumb steering is the default on iPhone and iPad: left thumb steers, right thumb fires, so your finger no longer hides Plobb (FOLLOW FINGER stays in OPTIONS). Fixed: with thumb steering you can now steer and fire at the same time. Feel the game: every pop, hit and explosion now has its own vibration, and game controllers rumble along. Your hall of fame travels with you through iCloud across iPhone, iPad, Mac and Apple TV. High scores earned offline are kept and sent to Game Center by themselves once you are back online. Shots fly all the way across the arena, slip out one side and fade back in from the other. Powerups stay with you through all levels of a world, right through its bonus round. iPhone and iPad now switch into Game Mode while you play: smoother performance, quicker controllers and AirPods.
