"Very cool 8^) - Fun old style arcade for us old arcade fans!" - Drewx67 "Great game - Awesome." - Goodluck74 "Nice retro watch game - Still loving this app. Fun to play on the watch while waiting in line or out and about. Quick hit gaming with fun retro feel. They keep on updating app too to make sure it works on OS updates. Thanks! Great retro game for the watch. It's like space invaders & block out combined! Works really well on the Apple watch. Uses new API's from watchOS 3. Nice scrolling with the crown and even uses the watch speaker for the great retro sounds. Love it! Next gen of watch games is here!" - peteostro "Excellent-- an iOS Classic! - I bought this game when the first version came out on iOS 2. It's been nearly 10 years and I still play it! I am so glad the developer keeps it updated. My favorite thing about it is the Commodore 64 SID sound effects and the speech synthesis-- this game would not look out of place in an early 80s arcade. The watchOS version plays very well on top of that! The Digital Crown makes moving the paddle a dream. Would definitely recommend this app to any retro game fan." - cyelvington "Gamers ... will likely find Space Invaders to be overly simplistic and outdone by most of its clones in the App Store such as Space Out." - http://toucharcade.com "I took a look at about 40 [games], I decided which ones lived up to the hype and which ones didn’t. One of my favorites was the game called Space Out." - Jamin Brophy-Warren, Wall Street Journal Online "Arkanoid + Space Invaders with the gorf voice thrown in for good measure! Sold." - GreatLakesDrifta Space Out is the original mashup, a tribute to old school arcade games; it truly delivers that early arcade feel. It combines 2 classic game concepts, shooting invaders and brick breaking, into a unique and exciting retro experience. It's a blast back to the late '70s. Complete with all new 8-bit sound effects created with a MOS 6581 SID chip from the Commodore 64 and speech generated with 8kHz 8-bit allophones. (Any control issues were fixed years ago.)
