By far the best Apple Watch game

Perfect graphics and gameplay for Apple Watch 4. It would be great to encounter a Boss after a set number of levels but I’m enjoying the game as is. Looking forward to seeing the next big update.

Developer Response ,

Thanks Mark, that is a great idea and something I'd like to add soon :-) The next update features 60fps on the Watch and the ability to play it on the iPhone too! Cheers, John

Solid variant on Gyrus

This plays real nice on Apple Watch. I didn’t like it as much on iPhone. It controls better with the Digital Crown. But I got this mostly for Watch, so that’s fine. Fun variation on the classic arcade game Gyrus. Nice graphics, fun and pretty challenging game. I wish it had more sound effects (and sliders to control volume), but the haptic feedback is cool.

Developer Response ,

Thanks for the review and feedback. We’re working on sound effects for the Apple Watch in an upcoming update.

Best Game but...

This is by far the best space shooter available. I have one request. Could you please add more lives? I feel like I can’t ever get very far in the game. My top score is about 100.

Developer Response ,

Thanks for the feedback, this is a great idea and will work well the upcoming boss stages due in an upcoming update!
