Update my Review/ Doesn’t work on iWatch

UPDATE: June 29, 2021
With my wife’s help, I reboot simultaneously my iPhone & iWatch together and now it plays fine on Apple Watch, with sound effects & music!
Great retro game play and very responsive. Good way to kill time at doctors appointment.

The game works well on my iPhone 📱 12 but I bought this for my iWatch, and after opening the game, it crashes. I’ve hard rebooted my phone and watch but no use. The link to developer website doesn’t work and no way to contact them. Hate to ask for a refund from Apple because I do like the game on my phone but doesn’t help me with my watch.

Developer Response ,

So sorry to hear this! I will look into why the contact link is not working. If you can let me know what model Watch it crashed on that will help - or email me at Thanks!

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.
