Ahhh, thanks. At times I swear I get hit by bullets, but then I make it out somehow- wasnt sure if there was some logic I wasn't aware of. Thanks for the response.
One option to check is the auto bomb option. If I remember..with the option enabled, if you have a bomb when you get hit, it'll drop maybe all your bombs instead of you dying. The trade off is any counter may be reset to 1. Benefit is you get another life..but the drawback is you may lose all your bombs in one go instead of being able to use it multiple times manually.
Yeah, it's funny, sometimes huge swarms of bullets come at you, and you think you got hit, but somehow, no hits register. Good thing though.
Just checked this morning and on my iPod touch 5 with iOS 7, I can install this game now. I don't get the missing digital compass message!
Interesting that a lot of people found this easy. Personally, I found 5A, despite being the easiest of the last levels, to be harder than every other iOS Cave shooter's last level on Normal and, in some cases, harder than Hard. That also mostly holds true for all the A levels insofar as they at the very least match their counterparts in other games on the Normal setting.
