Excellent game

Bought this game years ago and still play it. Also I tend to pass it to youngsters and challenge them with the levels. It’s really an excellent game and worth every penny.

An excellent app that could be so much better

This is one of my go-to games on my phone, as it's excellent gameplay, unique music, and addictive nature really makes it a long-time favorite. However, I feel like there's room for more levels. The lack of any real replay value once you beat all of the levels is a bit disappointing, but besides that, an excellent app that is great, but could be so much better. 8/10

Needs iCloud Save!

Great game, so much fun and extremely challenging. Just needs cloud save so our progress isn't for nothing. If there are no more levels to be added in the future then an update to save our progress in the cloud is the least to add. That would be really helpful and make this perfect. Thanks!
